Online Privacy Tools That Never Phone Home: Passwords, Hashes, and Tokens in Your Browser
The riskiest moment in using a free online tool is the paste. Most privacy guides rank browser extensions and VPNs and skip the question you actually face several times a week: when I paste a secret into a web page, where does it go? This guide covers the tools where the answer is verifiable, becaus
How Our BMI Calculator Works: The Formula, the Cutoffs, and the Edge Cases
Most BMI articles restate the same category table and stop. This one walks through the actual calculator we ship, line by line, including the inputs it rejects, the inputs it answers wrongly, and the design decisions behind them. You will know exactly what the number on screen means and where it sto
20-20-20 Rule Timer: What Our Eye Break Tool Does Every 20 Minutes
Most people meet the 20-20-20 rule as advice, follow it for one afternoon, and lose it the first time work gets loud. The rule fails as a memory task because it asks you to notice time while you are focused on something else. Our eye break timer exists because a browser tab can hold the clock so you
Learning Regex from Failures: Three Patterns That Broke Production
Most regex tutorials teach the happy path: literals, classes, quantifiers. The skill that separates a working pattern from a production incident is knowing the specific ways regexes fail. We collected three genuine failures from one codebase. Each one teaches a failure mode that no cheat sheet warns
Color Theory in Code: How Our Palette Generator Builds Harmonies and Checks Contrast
Color theory articles usually show color wheels and name feelings. This one shows the arithmetic. Our palette generator implements each classical harmony as a fixed rotation in HSL space, and our contrast checker implements WCAG luminance with gamma correction. Reading both reveals a trap most guide
Free vs. Paid Online Tools: The Real Cost of No Accounts
Every free versus paid comparison eventually becomes a list of feature checkboxes. We run one of the free sides of that comparison, this site, and the interesting facts are not feature rows. They are the engineering tradeoffs we accepted and the concrete price we already paid for the model. Here is
Web Development Tools 2025: The Stack That Actually Ships This Site
Every year brings another list of twenty web development tools nobody verified. This article is the opposite. It is a tour of the toolchain that builds and serves this website, with version numbers, resource limits, and costs taken from the repository on 2026-09-24. The site runs 164 tool routes and
Hashtag Strategy Starts With the Tag Set: What Our 8-Category Library Ships and How to Audit It
Our hashtag tool is a fixed library, and its exact contents matter more than any advice about timing or volume. It ships eight categories. Coffee, sport, travel, motivation, food, animals, photo, and fashion.
Merge and Extract PDF Pages in the Browser: The Range Rules Our Tool Follows
You need to send one document, and it is spread across three PDFs. Or you need pages 4 through 7 of a 60 page contract and nothing else. Both jobs are small, and both are usually solved by uploading private files to a random website and hoping the deletion policy is real.
White Noise Without Audio Files: How a Browser Mixes Rain, Wind, and Thunder
Most white noise websites stream an audio file. Ours ships none. The mixer generates every sound in your browser from raw random numbers, then shapes that noise with audio filters until it reads as rain or surf. Knowing how that works changes how you use the tool, because it tells you exactly what y
Date Difference Calculator Uses, Limits, and One Borrow Bug
Subtracting two dates sounds trivial until the answer needs to survive a leap year, a short month, and a timezone. Our date difference calculator is roughly thirty lines of arithmetic, and reading those lines explains exactly when to trust it and when to route around it. This article covers what it
Lorem Ipsum Without Randomness: Inside a 59-Word Generator
Paste the default output of our lorem ipsum generator into two different mockups and you get identical text. The tool contains no random number generator. Every designer who opens the page with the same slider settings sees the same paragraphs, in the same order, every time. That is a design decisio
How to Convert HEIC to JPG in the Browser: What the Decoder Actually Does
You copied photos off an iPhone and the upload form, the CMS, and your coworker's laptop all reject them. The files are HEIC, Apple's container built on the same compression family as HEVC video. Safari and Apple hardware read it natively. Most of the rest of the web does not. Conversion to JPG is t

Need to copy text from a screenshot, scanned document, or photo? Learn how OCR works, when to use it, and how to extract text from any image for free in your browser.
CSS Box Shadow Guide: Reading the Output of a Real Generator
Syntax guides list box-shadow values and call the last three optional. A generator cannot leave anything optional, because it emits one string per state. Ours writes every value, always in the same order, always with the same units. Learn to read that string and every tutorial example becomes trivia

Block Stacker Strategy from the Source Code: Scoring, SRS, and the Speed Curve
Falling-block guides usually recycle scoring folklore. This one reads the engine. Block Stacker, our browser game, implements the modern standard mechanics, and each constant in the source implies a specific strategic decision. Once you know what the code pays for, the correct openings and endgame habits follow from ari
Sudoku Solving Techniques: The Logic Ladder Our Generator Has to Guarantee
You are stuck on a grid with two empty cells left in a row and no instinct for which digit goes where. Guessing feels natural here, and on our puzzles it is never required. Every board our Sudoku engine ships has been checked to have exactly one solution, so a logical deduction always exists. This a
Word Guess Strategy From a 200-Word Bank: Open With CEDAR
Standard advice for five-letter word puzzles ranks starting words by letter frequency across all of English. Our Word Guess game ships with a fixed 200-word answer bank, and we measured it. The bank disagrees with the standard advice in one important way, and the correct opening move here is different from the one most guide
2048 Tips and Tricks Read Straight from the Game Engine
Most 2048 advice is folklore passed between clones with different rules. This site ships its own engine, so every claim here can be checked against src/games/game2048/Game2048Engine.ts. Read the four rules below first. Every tactic follows from them.
Snake Game History Told Through Its Mechanics: From Blockade to a 60 ms Tick
Most histories of Snake list years and devices. This one lists rules. The game survived five decades because a handful of mechanical decisions travel well across hardware, from a 1970s arcade board to a canvas element in your browser. Our own implementation makes those decisions explicit in code, so

What Is SEO? The Basics Read From a Real Indexing Record
Most SEO explainers describe a machine nobody shows you running. This one walks through the crawl, index, and rank pipeline using dates and counts from our own Search Console account for webrecast.com. Every number below came out of a GSC API pull or a Lighthouse run we saved in this repository. Whe
How to Do Keyword Research With 11 Impressions: The Method We Actually Use
Standard keyword research starts with search volume. On 2026-09-18 our Search Console record for the previous 30 days held 11 impressions and 1 click. There is no volume data to mine in that, and most new sites sit in the same position. This is the method we use instead, built from our own roadmap f
Backlink Quality: What a Site With Zero Links Learns Earning Its First Twenty
Generic backlink advice is written by sites that already have links. We are writing from the other side: webrecast.com launched with zero external links, and our Search Console record shows exactly what that costs. This guide defines link quality through the plan we built to earn our first 20 to 30
Local SEO on Google Maps: Measurement Discipline From a Site With No Storefront
We run a global tools site with no physical location, so we cannot hand you a local pack case study. What we can hand you is a fully documented measurement record from Search Console, plus the decisions it forced. Local SEO runs on the same machinery: one canonical profile, pages that earn their pla
Meta Descriptions and Title Tags: The Length Rules Our Own Site Enforces
Most advice about meta descriptions and title tags quotes character limits that nobody can verify, because search engines rewrite snippets on their own schedule. This article takes the opposite approach. It documents the title and description rules enforced by our own static shell renderer, the code
Email Marketing Strategies: What Our Own Distribution Numbers Force Us to Test
We published 180 articles. Search Console credited them with 11 impressions and 1 click over the 30 days measured on 2026-09-18. Most email marketing advice opens with a return-on-investment figure that we cannot verify from any log we own, so this article does not repeat it. What we can verify is t
Social Media Algorithms Explained: What You Can Measure and What Nobody Can
Articles that explain a social feed read like they have seen the source code. They have not. No platform publishes its ranking weights, so every precise-sounding claim about them is reconstruction. We run a website with a 30-day distribution record we can show, and this article uses it to separate w
Google Search Console Guide: What Four Weeks of API Audits Found
Between 2026-09-16 and 2026-09-24 we ran four scheduled Search Console checks. Each inspected 20 URLs through the URL Inspection API. Zero pages moved into the index across all four runs. This guide documents the workflow that produced those reports, the exact calls, the coverage states we observed,
Content Marketing Mistakes Our Own Data Caught
We publish on a site that publishes a lot. The numbers above are ours, and they caught us making four content marketing mistakes that every guide warns about in the abstract. The data made them concrete. Here is each mistake with the measurement that exposed it, so you can run the same measurement o

How to Pair Fonts: Four Working Defaults and the Fallback Bug to Fix
Copy the CSS from a font pairing tool, paste it into your stylesheet, and you can ship a fallback stack that contradicts your own font choice. Our font pairer has this exact bug in its copied output. This article walks through the four default pairs the tool ships, the rules behind them, and the thr
WCAG Contrast Checker: The Exact Formula, Four Thresholds, and a Worked Example
A designer hands you a palette, and two of the text pairs are unreadable for a meaningful share of users. Arguing about it is slower than computing it. This guide explains the WCAG contrast checker we ship at the source-code level, so you know what the number on screen means, where it comes from, an
SVG Editor Guide: Sanitize, Validate, and Recolor Vector Code in the Browser
You exported an SVG from a design tool and you need one thing changed: a color, a dimension, or a cleanup pass before it ships. Full design suites are the wrong tool for that job. This guide covers the browser-based SVG editor we ship, including the parts it deliberately refuses to do, because knowi
CSS Border Radius Generator Values: Corner Order, Presets, and the Clamping Rule
Four numbers in, one declaration out, and still border-radius produces bugs in review. The causes are predictable: corner order, unit choice, and a clamping rule that fires when adjacent radii overlap. We ship a border radius generator, and its own presets demonstrate all three, including one preset
Glassmorphism CSS Generator: The Exact Output It Emits and Where It Breaks
Glassmorphism sells a specific promise: a card that looks like frosted glass floating over your background. The reality is five CSS lines, and most tutorials hand you a snippet without saying which parts are safe to tune or what happens in browsers that ignore the effect. This guide documents the ge
CSS Text Shadow Generator: Typography Effects From the Exact Output
Most text shadow tutorials show finished effects and skip the decisions a generator has to make. Ours emits one exact string per state, and reading that string teaches the property faster than any gallery. This article walks the real component, the five presets it ships with their actual values, and
Calorie Calculator: The Mifflin-St Jeor Math Our Tool Runs
A calorie calculator prints four numbers and looks authoritative. The useful question is where each number comes from, because two of the four are pure arithmetic and two depend on a multiplier you pick by feel. Our tool runs the Mifflin-St Jeor equation, and this article walks the exact path from y
Daily Water Intake Calculator, Explained to the Last Milliliter
Most hydration calculators hide their math behind a label. Ours is three lines of TypeScript in src/components/WaterIntake.tsx, so the honest thing to do is open it up. Here is the exact formula, worked examples with the real rounding behavior, and the inputs the formula deliberately ignores.
Sleep Cycle Calculator: The Exact Math Behind Your Bedtime
You set the alarm for 07:00, you sleep roughly eight hours, and you wake up groggy anyway. A sleep cycle calculator attacks that problem from one direction. It cannot see your sleep, so it works from the average structure of a night and tells you when to be asleep already. Here is the exact arithmet
Heart Rate Zone Calculator Math: Both Formulas With Worked Numbers
Enter age 30 with a resting heart rate of 60 into a zone calculator, then delete the resting value and recalculate. On our tool, zone 2 moves from 138 to 151 bpm down to 114 to 133 bpm. Same person, same age, 24 beats of difference, and the tool switches formula without telling you. This article run
Body Fat Percentage Calculator Guide: The Navy Formulas, Constants, and Failure Modes
We rebuilt our own body fat calculator with a spreadsheet next to the code, and the exercise found one discrepancy worth publishing, one edge case that mislabels a lean person, and one input that breaks the display. This guide walks the actual formulas, then the failure modes, so you know precisely
Pregnancy Due Date Calculator: How Our Week Tracker Computes Every Number
Most pregnancy calculators show you a date and hide the arithmetic. This article opens our own component and shows every computation, including the inputs it refuses and the one thing it does not ask for. You will be able to reproduce every number on screen with a calendar.
SQL Formatter, Rule by Rule: What Happens to Your Query Before You Copy It
A SQL formatter sounds like a parser. It rarely is. Ours applies five regex rules in a fixed order, and knowing that order tells you when the output is trustworthy and when it quietly changes what you wrote. Here is the pipeline, rule by rule, with the places it bites.
Three Data Pipeline Bugs That Only Bit During Conversion
Converting between data formats is where assumptions die. The file looked fine, the parser looked fine, the pipeline returned success, and the output was wrong. Three bugs from one real migration, each a pattern that will visit your CSV and JSON pipelines too.
Cron Expressions in Production: Schedules We Run and What They Cost
A cron expression is five fields that decide when something runs. Most guides stop at the syntax. The part that matters in production is what a schedule costs when it fires, what happens when it overlaps itself, and how you notice silence. We run a small fleet of scheduled jobs, and their behavior t
Color Code Converter: HEX, RGB, HSL Conversion and Comparison
Understand the differences between HEX, RGB, and HSL color formats. Learn when to use each format and how to convert between them.
GPA Calculator Math: Credit Weighting on an 11-Grade Scale
Your transcript says one number and a web calculator says another, and the difference is almost never a typo. It is the scale, the credit weighting, or the rounding. We document our own GPA calculator the only reliable way, by reading the code line by line, so you can predict its output before you c
Percentage Change With a Negative Base: Why Our Calculator Divides by the Absolute Value
Percentage questions look harmless until the numbers turn negative. A profit of 50 follows a loss of 50. Did things improve by 200 percent, or did the formula produce a nonsensical negative because the starting value was below zero? Most calculators never tell you which convention they used. Ours do
Inside Our Online Scientific Calculator: Degree Conversion, log vs ln, and the Percent Trap
The calculator does not parse your expression with a custom engine. It rewrites it into a JavaScript arithmetic expression and evaluates that.
Area Calculator Formulas: Seven Shapes, Four Decimal Places
Most area calculator pages list formulas and stop. The failure cases appear when a tool and a textbook disagree about what area means for a solid, or when an input edge case quietly changes your result. We rebuilt our own geometry calculator documentation by reading the implementation, and this arti
Equation Solver Edge Cases: a=0, the Discriminant, and a Floating Point Trap at Six Decimals
An equation solver looks like the simplest tool on a site like ours. Enter three coefficients, get roots. The interesting part starts where the clean math meets JavaScript numbers. We maintain the solver, and this article covers the edge cases we chose, the one we report incorrectly on purpose, and
How Our Chemical Equation Balancer Works: Coefficients, Caps, and Rejected Equations
The balancer shows a single text box and one button. Behind them runs a bounded brute-force search that tries integer coefficients in ascending order until every element count matches on both sides. That design choice creates hard limits, and this article documents each limit with the exact outputs
Interactive Periodic Table: How to Read 118 Elements From Their Data
A printed periodic table rewards memorizers. An interactive one rewards people who ask the data questions. Ours carries 118 elements as raw tuples and renders them as clickable cells. Click any element and a panel opens with its atomic number, atomic mass, and category. That is deliberately small, a
Number Base Converter Internals: Binary, Hex, Octal, and the 2 to the 53 Wall
Converting between binary, hex, octal, and decimal is textbook material. The interesting parts of a real converter are the edges, which inputs get rejected, why parseInt alone is dangerous, and where floating point silently corrupts results. This site ships a number base converter, and its source co
Paint Calculator Math: The Exact Formula Behind Our Room Coverage Estimate
Our paint calculator treats the room as a rectangle and computes wall area with one line of code.
Electricity Cost Calculator: The Watt-Hour Math Behind Your Bill
Your bill totals every appliance together, so the number that shocks you each month points at nothing. You need one device broken out, one month at a time. That decomposition is a four-field calculation, and our electricity cost calculator runs exactly the version described below.
Mortgage Amortization Math: The Formula Our Calculator Runs, With a Verified Example
Our mortgage calculator uses the standard annuity formula for a fixed payment loan.
Tip Calculator Math: The Exact Formula Chain and the One-Cent Split Gap
The hard part of tipping is rarely the percentage. It is the split. Four people each pay a number that quietly disagrees with the bill total by one cent, and nobody wants to be the person who mentions it. Our tip calculator's arithmetic is simple enough to state in full, and its rounding order expla
Age Calculator Arithmetic: Month Borrowing, Leap Days, and the 31st Problem
Subtracting two dates component by component looks correct until the birth day is larger than the current day. Then you borrow, and the borrow rule decides whether your age in years, months, and days is right. Our age calculator's rule is simple enough to state in four steps, and it carries a real e
Time Zone Converter Arithmetic: Fixed Offsets, Day Rollover, and the Half-Hour Bug
Converting a meeting time between zones is subtraction on offsets. The failure modes live in three details: day boundaries, half-hour zones, and summer time. Our time zone converter implements the plain arithmetic version with 12 fixed offsets, and its exact limits are worth knowing before you trust
Cooking Measurement Converter: The Exact Constants Our Kitchen Tool Uses
Most kitchen conversion errors do not come from bad arithmetic. They come from chained conversions, rounded along the way, stacked until the cake fails. Our cooking measurement converter avoids the chain problem by storing one exact factor per unit and converting in a single step. This article lists
Shoe Size Converter Tables: Exact Rows, Closest Matching, and the Tie That Rounds Down
No formula converts a US shoe size to an EU one, because the systems were never defined from one another. Each scale grew around different lasts and different reference foot lengths. Our shoe size converter therefore ships lookup tables instead of equations, and matches your input to the nearest tab
How to Check Your Google Ranking Without Guesswork

We run a web tools site, we track our own traffic in Google Search Console, and our record for one 30 day window reads 11 impressions and 1 click. That number is exact, because it comes from a prop
Regular Expression Examples: Learn Regex by Solving Real Text Problems
Understand regular expressions with practical examples for emails, URLs, numbers, whitespace, and search patterns.
Age Calculator Edge Cases: Leap Days, Month Ends, and Two Counting Methods
Date math looks safe until the day count comes back negative. That can happen in our own age calculator, with real inputs, and this article shows exactly how. We ship two related tools, the age calculator and the date difference calculator, and both share one calendar algorithm. Knowing where that a
Time Zone Planning with a Fixed-Offset Converter: What Converts Cleanly and What Bites
Scheduling across time zones fails in predictable places: half-hour offsets, midnight crossings, and daylight saving. Our converter and countdown tools handle the first two by design and cannot handle the third, because they use fixed offsets. This guide shows exactly what the code does, where it is
Pomodoro Timer Break Rules: How Our Tool Handles 25, 5, 15, and Every Fourth Session
Most Pomodoro guides tell you to work 25 minutes and rest 5. They skip the part that decides whether the routine survives the second day: what the timer does when it hits zero. We maintain a Pomodoro timer on WebRecast, and every break decision in it is a rule you can inspect in the source. This art

HTTP 429 Is Not a Traffic Problem: How a Rate Limit Silently Broke Our Search Traffic
HTTP 429 means "too many requests". Most teams treat it as a polite way to slow down scrapers. That is a mistake. Google treats a 429 the same way it treats a 5xx server error, and it will drop pages from Search Console reporting under "Server error (5xx)" without telling you the real status code.
Sitemap lastmod: Why Google Stopped Downloading Ours for Two Months
Google does not promise to read your sitemap. It proved that to us with two months of silence: our sitemap said lastmod August 16, and Search Console still showed "last downloaded July 3". Every page we shipped in that window was invisible to the crawler, and nothing anywhere raised an alarm.
Our Build Script Segfaulted Node for a Week: The Regex Behind It
A segfault in a Node script feels like a broken runtime. Ours was not. A single regex, executed hundreds of times against a large file, overflowed the regular expression engine's stack and took the whole process down with exit code 139. The same code ran fine on smaller inputs for months.
LCP in a React SPA: Why Preloading the Image Fixed Nothing
Our largest contentful paint was a 15 KB image. It loaded from the CDN edge in under 300 ms, cached, compressed, correctly sized. Lighthouse still reported 3.7 seconds. If you run a single-page application, the LCP number measures your JavaScript boot time, not your image delivery, and optimizing th
15 Languages, One Indexed: The noindex Strategy We Chose and When We Will Reverse It
WebRecast publishes in 15 languages. Google is allowed to index exactly one of them. Every non-English page ships a robots meta tag reading noindex,follow, while the sitemap lists only English URLs.
Image Compressor Quality vs Size, What the Slider Does
You drop a photo, move a quality slider, and watch a percent smaller figure update. Most guides stop at "use 70 to 80 percent". We maintain the image compressor on this site, so we can show you what the slider actually sends, which numbers are fixed in code, and the two places where the tool changes
YouTube Thumbnail Downloader Formats, Four Files Per Video
Thumbnail grabbers advertise 4K covers. YouTube actually serves every public video a fixed set of four JPG files, and the largest standard one is 1280 by 720 pixels. We run a YouTube thumbnail downloader on this site, its code requests exactly those four files, and the details below come straight fr
Password Generator Entropy Explained, Pools Bits and Bias
Strength meters hand out labels. Entropy gives you a number you can check with a calculator. Our password generator ships with a 62 character default pool and a 16 character default length, and those two facts fix the strength of everything it prints. Here is the arithmetic, plus one bias in our own
Markdown Editor Rendering Pipeline, Keystroke to HTML
The preview pane of a Markdown editor updates on every keystroke. That immediacy hides a pipeline with exactly two parser options, and both options change how your text renders on other platforms. This is the pipeline in our own Markdown editor, stage by stage, including the two failure modes we acc
Text Diff Algorithms Compared, LCS vs Myers
Every diff tool promises to show what changed. The algorithm underneath decides how small the change looks, how fast the tab responds, and what a rewritten line costs you. Git ships the Myers algorithm. Our text diff checker ships the classic longest common subsequence dynamic program. Here is both,
Robots.txt Directives Explained: What Our Generator Writes and What It Silently Omits
We built a robots.txt generator and then read its output line by line before trusting it. That audit caught three behaviors that surprise people. The tool starts every new block with an empty Disallow path. It drops the Crawl-delay line whenever the value is 0. Its Block AI preset writes four separa
OG Tag Previewer Fields Guide: Five Inputs, Two Limits, One Silent Failure
We audited our OG tag previewer field by field before documenting it, because the tool makes choices a user cannot see. It always appends an og:type line to the copied tags. It drops the preview image without a warning when the URL fails to load. It clamps text by line count, and the counts differ p
Keyword Density Limits: The Reality Behind One Percentage Number
We opened our keyword density analyzer to check where its numbers come from, and the formula hides two decisions that change every result you see. The denominator counts every whitespace separated token in your text. The numerator counts matches after lowercasing, after stripping punctuation, and af
Site Explorer Recon Workflow: 14 Checks in One Fixed Order
We built a site explorer that answers one question per click, and the useful part turned out to be the order of the clicks. The tool places 14 links on one page, grouped into search engines, archives and WHOIS, and performance. Run in the wrong order, the checks waste time, because a DNS or SSL prob
Traffic Overview Snapshot Method: One Month, Seven Columns, One Honest Rule
We track our own traffic as monthly snapshots, and the recording method matters more than the dashboard. Our traffic overview tool stores one row per month with seven columns, refuses to show a trend when it has no valid baseline, and replaces a month on resubmission instead of keeping both. Each of
JWT Decoder Checklist: Three Parts, One Padding Fix, and an Expiry Trap
You paste a token into a decoder, you get JSON back, and you move on. The problem is what the page did not check before showing that JSON. We read our own decoder line by line and ran the arithmetic to pin down exactly which checks run, which values are trustworthy, and where the badge can lie to yo
Hash Generator Algorithms Compared: What 128 to 512 Bits Actually Buy You
Five hash algorithms in one page, all updating as you type, and no guidance on which row to copy. We ran all five algorithms on fixed inputs, read the implementation behind each row, and compared the results. This is what the sizes mean, which engine computes each digest, and where each algorithm be
URL Encoding Percent Guide: Both JavaScript Functions, Verified Side by Side
A link breaks because one space or one ampersand in a query value was sent raw. You reach for an encoder, discover two JavaScript functions with similar names, and now the bug depends on which one you picked. We ran both functions on the same inputs and documented where their outputs diverge and whe
HTML Entity Escaping Rules: Five Characters, One Order, and a Table Bug We Found
Escaping HTML is a small ruleset done in a fixed order, and most breakage comes from changing the order or escaping too much. We read the exact replacements in our own encoder and tested the decode path. The rules fit in one page, and one defect in our reference table proves why you should verify ta
Code Minifier: What It Removes, What It Keeps, and What It Can Break
Minification is deletion under constraints, and the constraints are where the damage happens. We ran the exact minifier functions from our component on fixed samples and hostile edge cases, and we measured every number in the stats bar. Here is what the tool deletes, what it protects, and the four i
Color Code Converter Formats: Inputs, Outputs, and Roundtrip Drift
Paste a 12 color palette into a design handoff and convert each value by hand and you spend an afternoon injecting typos. Our color code converter takes the whole list at once and returns five formats per line. Three of its parsing and rounding rules surprise people regularly, so this article docume
CSS Gradient Syntax Anatomy: What Every Token in the Output Controls
A generated gradient looks like one opaque string that you paste and hope for the best. It is really three token groups, and each group maps to one control in our CSS gradient generator. Break the string into those groups and you can edit any gradient by hand when the visual editor is not open.
QR Code Error Correction Levels: How L, M, Q, and H Change Your Code
Every QR code generator asks one question before you download, and most people click through it. The error correction level decides how much of the printed code can be damaged before a scanner gives up. Our QR code generator ships four buttons for it, and picking the wrong one either wastes print sp
TeamSpeak Avatar Size Rules: What the 320 Pixel Cap Does to Your File
Upload rejection on a TeamSpeak server usually comes down to numbers, not content. Avatars that come straight off a phone are thousands of pixels wide and megabytes heavy. Our TeamSpeak avatar resizer exists to enforce one dimension rule and report the rest, and knowing exactly which rules it enforc
Decision Wheel Fairness Audit: Equal Slices and One Uniform Draw
Spin a decision wheel a few times, one option keeps winning, and everyone accuses the wheel of cheating. So we audited our own decision wheel the way you would audit a coin, by reading the code that produces each result. The short version is that the geometry is fair by construction, the animation c
Bold Text Generator Unicode Math: Eight Style Blocks and Thirteen Exceptions
Type hello into a bold text generator, copy the bold result back into a search box, and you get zero matches. The styled word consists of different code points than the one you typed. That single fact explains most failures people hit with Unicode text styles, so this article documents the exact map
Small Caps Generator Character Coverage: Real Glyphs, Stand-Ins, and Gaps
A small caps generator that claims to convert your text oversells what Unicode can do. The Unicode standard simply lacks glyphs for several letters in several styles. We audited every map in our own small caps generator, and this article reports the exact coverage, including the one letter that gets
Upside Down Text Generator Quirks: Borrowed Glyphs, Bracket Logic, and Zalgo Counts
Upside down text is not rotated. It is a substitution cipher followed by a string reversal, built from whatever glyphs Unicode happens to offer. We opened the map inside our own upside down text generator and counted every entry, and the results explain why flipped text looks convincing for some wor
Online Notepad Persistence Model: What the Saved Label Actually Guarantees
An online notepad shows a green Saved indicator and people trust it like a file on disk. The label promises less than they assume. We built the tool, and this article documents its persistence model exactly as the code implements it, including the half second window in which your last keystrokes exi
Unit Converter Factor Sources: The Exact Numbers Behind Every Conversion
Every unit converter is a table of constants wearing a user interface. We pulled the table out of our own unit converter and checked each factor against its reference definition. The audit found factors that are exact by definition, factors truncated at roughly one part per million, one mislabeled s
Laundry Symbols Decoded: Every Icon in Our 33 Symbol Care Dataset
Care labels compress five separate instructions into rows of tiny graphics. One misread row shrinks a wool sweater, melts a print, or turns a white shirt gray. This guide decodes the 33 laundry symbols our translator tool actually ships, group by group, using the temperature and solvent values store
Plastic Recycling Numbers 1 to 7: What Our Lookup Dataset Actually Flags
The number inside the recycling triangle names the polymer. Our plastic numbers tool stores all seven codes, each with four capability flags and a safety rating, and the flags carry one trap worth knowing before you microwave anything.
Traffic Sign Shapes and Meanings: 52 Signs Sorted by What the Shape Tells You
At speed you register a sign's shape and color before you read anything on it. Shape tells you the message class, and the class tells you what to do. Our traffic signs guide stores 52 entries, and every one belongs to exactly one of four shapes.
Dashboard Warning Lights Priority: 20 Lights in Four Color Levels
A light appears on the dash while you drive. Your first decision is the color, and the icon comes second. Color sets the urgency, and our dashboard lights tool encodes that priority as four levels across 20 lights.
AC Remote Symbols Decoded: 22 Functions in Four Groups
An air conditioner remote hands you a grid of icons with few words. Two of those icons decide most of your comfort and most of your bill. Our AC remote tool decodes 22 functions in four groups, and this guide walks the same 22 in the order you actually press them.
Debugging an API with curl: Three Real Sessions
curl is not a download tool with flags. It is a request builder that shows you exactly what an API saw, which makes it the fastest debugging instrument you own. Here are three API problems we solved with it, each in under ten minutes, each a pattern you can copy.
Image Format Converter Pipeline: Three Outputs and One White Fill
Most image converters advertise a long input list and hide a short output list. Our format converter does the opposite. The code exposes three output formats, JPEG, PNG, and WebP, and treats everything else as input. This article walks the actual pipeline in the component, including the one branch t
Text Tools Case Operations: Eight Transforms and Their Edge Cases
A case converter that works on a two-word sample tells you nothing. What matters is what it does to a contraction, to an accented word, and to a list with hundreds of near-duplicate lines. Our text tools page runs eight transforms and six live counters, and this article documents where each one beha
VP and Robux Value Math: How One Rate Rules the Estimate
Game currency calculators usually quote one price and stop. Ours derives a rate from a specific package, and which package it picks matters more than the number you type. This article shows the exact math inside the VP and Robux calculator, using the price tables shipped in the component, and points
Meeting Cost Hourly Burn: The Math Behind the Running Total
A meeting cost counter is only as honest as its denominator. Ours divides monthly gross salary by 633,600, which is 22 working days times 8 hours times 3,600 seconds. This article walks through every number the tool derives from that constant, including one multiplier the interface stops showing you
Car Rental Fine Print: Excess, Deposit, and the Damage Form
Rental counters win disputes on fine print, and two numbers decide most of them: the excess and the deposit hold. Our car rental glossary tool encodes 16 terms across three tabs and flags 7 of them as dangerous. This article pulls out the terms that cost money, states what each one means, and turns
Farm Chemical Dosage Formula: The Tank Math Our Calculator Runs
Product labels state a dose per decare. Your sprayer holds a fixed tank. The number you need at the mixing site is the amount per tank, and that conversion is where most mixing errors happen. Our farm chemical calculator runs one formula and prints its substitution live under the result. This articl
Ceramic Tile Waste Factor: How Ten Percent Becomes Sixteen Boxes
Tile sellers quote boxes. Rooms measure square meters. Between the two sits the waste factor, the percentage you add so cuts, breakages, and future repairs do not stop the job. Our tile calculator ships a waste slider from 5 to 25 percent, defaulting to 10. This article traces how that percentage tu
Macro Calculator Split Ratio: The Fixed 30/45/25 Behind Your Grams
Our macro calculator returns three calorie figures, three macro gram targets, and one water line. Most articles explain what macros are. This one documents the arithmetic our component runs, including one place where our own page copy and our code disagree, and one label in the result chart that rea
AI Prompt Template Anatomy: What Our Generator Actually Assembles
Most prompt generators show you one output and hide the template. Ours assembles three strings from four parts, and every part is visible in the source. This article takes the template apart so you know exactly what you paste into Midjourney, DALL-E 3, or Stable Diffusion, including two translation
CPS Test Measurement Window: How the Timer Decides Your Score
A clicks per second score is only as meaningful as its measurement window. Our CPS test offers four windows, 5, 10, 15, and 30 seconds, and the same hand produces very different scores across them. This article documents how the timer decides what counts, when it stops, and which of the two CPS numb
Jewel Crash Match Rules Read Straight from the Engine
Most match-three guides assume rules the clone in front of you does not have. This site ships its own Jewel Crash engine, so every rule below comes from its source. Read the rules once and your swaps stop being guesses.
Minesweeper First Click Safety Rules from the Engine
Every Minesweeper player asks whether the first click can kill them. In this implementation the answer is fixed in code, and the same file answers where to open, whether flags are required, and why some endgames are pure luck.
Sky Hopper Gap Randomness Measured from the Engine
Sky Hopper feels unfair because gaps seem to conspire against you. The engine in this repo shows exactly how much of that feeling is real. Every gap center is an independent random draw, and every other difficulty number is fixed and knowable in advance.
Breakout Paddle Physics Decoded from the Source
The paddle in Breakout looks like a flat wall. The engine treats it as an aiming device, and the exact reflection rule decides which plays pay and which only look good.
Memory Match Pair Strategy Built from the Card Engine
Memory games get sold as pure concentration. The rules that actually decide your result are structural, and this engine fixes all of them. How many shapes exist, how long you see a wrong pair, and which number the game saves as your record are all in the source.
Hangman Word Bank Audit: The 250 Words Behind Our Engine
Most hangman guides quote letter frequency from English corpora. That advice fails here because this site ships a fixed bank of 250 uppercase words in src/games/hangman/HangmanEngine.ts. This audit counts the actual bank, so every percentage below is checkable against the source file.
Nonogram Logic Rules the Puzzle Engine Actually Enforces
Generic nonogram guides teach rules the target app may not implement. This site ships its own engine, so every rule below is tied to specific code in src/games/nonogram/NonogramEngine.ts. Read the enforcement rules first, then the solving order.
Solitaire Deal and Shuffle Rules Straight from the Engine
Solitaire advice usually assumes a paper rule set. This site runs a specific Klondike engine in src/games/solitaire/SolitaireEngine.ts, and several of its rules change correct play. The deal, the scoring, and one movement quirk are documented below with exact numbers.
Tower Defense Wave Economy Numbers from the Engine
Tower defense guides quote upgrade prices from whatever clone they played. This site ships one engine in src/games/tower-defense/TowerDefenseEngine.ts, and its economy is fully written down. Every cost, hit point, and income figure below comes from that file.
Arena Duel Combat Math Written in the Engine
Gladiator guides for this genre deal in vibes. Arena Duel runs on a single engine file, and every roll is written down. The formulas below are the whole fight, followed by the numbers that decide character creation.
Maze Chase Ghost Logic Audit, Four Targets and One Clock You Can Count
Most maze game guides describe the ghosts by personality. Maze Chase ships the personalities as arithmetic you can read in getGhTarget and moveGhost. Audit the four rules below and the maze becomes a schedule you follow instead of a chase you fear.
Alien Defense Bullet Speed Facts That Set Your Fire Discipline
Your bullet climbs at 480 pixels per second. The bottom alien row sits 600 pixels above your firing point at level 1, so your shot needs 1.25 seconds to reach it. The top row sits 760 pixels up and needs 1.58 seconds. Those two flight times set every firing decision in the game, because you own only
Paddle Ball Paddle Angle Control, the 60 Degree Contact Rule
Angle control in Paddle Ball is one formula. Where the ball meets your paddle fixes the return angle, and nothing else about the shot matters. Our engine computes it in deflectBall. Learn the contact zones and you pick every return angle on purpose.
Sketch Jump Platform Spread, the Gap Odds Your Generator Rolls
Every Sketch Jump run ends at a gap you misjudged. The spread between platforms in this build is a formula you can read, and your jump is a fixed 137 pixel arc. Compare the two and you know which gaps are a choice and which are a death sentence before you leave the platform.
Fruit Slicer Slice Detection, the Blade Math Behind Every Combo
Fruit Slicer feels like it rewards fast slashing. The engine rewards geometry. Every slice you land passes one of two exact hit tests, and every combo you earn is a counter with two reset points. Read the detection math and your swipe pattern changes immediately.
Bubble Shooter Bounce Angles Read from the Engine Code
When the direct lane to a same-color cluster is blocked, the bounce off the side wall is the only way in. This bubble shooter build ships its own engine, so the bounce geometry, the snap rule, and the scoring multipliers are all fixed numbers you can plan around. Read the four rules below before you
Cube Dash Obstacle Patterns Decoded from the Level Generator
Cube Dash feels random until you read the generator. This build assembles each level from twelve fixed obstacle patterns chosen by a deterministic formula. The cube, the gravity, and the jump arc are equally fixed. Every number below comes straight from the engine, and the strategy follows from
Color Gate Cycle Timing Explained by the Rotation Code
Every death in Color Gate comes from touching a ring segment whose color does not match the ball. The rings rotate at speeds the engine computes from a formula, so the safe window is a number you can count, not a feeling. This build runs on its own engine, and every timing below is taken from the
Mole Smash Window Math from Spawn Odds to Combo Thresholds
Mole Smash looks like a reflex test, but the engine behind this build reduces it to arithmetic. Every mole type shows for a computed duration, every tap checks a 66 px radius, and the combo ladder climbs at fixed hit counts. Here is the window math, straight from the spawn timers.
Road Hopper Lane Speeds and Timings Straight from the Engine
Road Hopper kills you in four ways, cars, water, trains, and the screen push, and every one of them runs on a speed or timer you can read from the engine. This build generates its lanes from fixed formulas. Learn the four clocks below and each crossing becomes a computed decision.
Tower Bounce Rotation Control Read From the Engine Constants
You lose Tower Bounce when the tower sits a few degrees off at the moment the ball crosses a ring. This site ships the engine, so the rotation tolerances are not guesswork. Every number below comes from src/games/helix-jump/HelixJumpEngine.ts.
Stack Game Slice Tolerance and the 4 Pixel Perfect Rule
Every placement in the stack game is judged by one comparison, the offset between the moving block and the top block. When that offset is 4 pixels or less, the engine calls it perfect. Everything about tower width follows from that single threshold in dropBlock.
Knife Throw Timing Windows From Flight Time and Collision Angles
In Knife Throw you do not miss because you aimed at a knife. You miss because the log kept turning during the 156 milliseconds your knife spends in the air. The engine fixes that flight time and every collision angle, so the lead you need can be computed exactly.
Water Sort Solvability and How the Generator Proves Every Board
A water sort board that cannot be solved is a design failure, and this engine refuses to ship one. Before a level reaches your screen, the generator either proves a solution exists or rebuilds the board from a solved state by playing backwards. The rules below turn that guarantee into a solving orde
Tall Man Run Growth Curve and the Gate Math Behind It
Tall Man Run tracks one number, your height, and every gate applies one of four operations to it. The boss at the end of the track compares that number to its own. Read the gate math and the whole growth curve becomes a set of if-then rules.
Parking Jam Unblock Order Rules Read from the Engine
Random slides solve the easy boards and strand you on the hard ones. The engine holds a fixed definition of which car blocks which, and it grades every slide you make. This article turns that code into an unblock order that applies to all 25 levels.
Balloon Guard Balloon Durability: One Hit Ends the Run
The balloon in Balloon Guard has no health bar and no recovery state. checkBalloonCollisions tests one circle of radius 28 against every obstacle, and the first overlap calls popBalloon and ends the run. Durability in this game is a property of your shield work, so treat any advice about balloon HP as fic
City Hole Absorb Radius Thresholds and Growth Math
Most City Hole losses are threshold losses. Your hole sits at radius 34 while a car sits untouched in front of you, because the engine only lets a hole swallow an object once its radius passes that object's entry in SIZE_THRESHOLDS. Knowing the table turns a round of wandering into a route.
Gladiator Quest RPG Combat System: Formulas from the Engine
Every fight in Gladiator Quest RPG resolves through fixed formulas, and you can read all of them in the store slices. This article lists each formula, then builds a turn routine and a training budget from the numbers. A new gladiator starts at level 1 with 100 HP, 150 gold, and all stats at 5.
Zigzag Turn Timing: How the Engine Judges Every Tap
A tap in Zigzag does not move the ball and does not score. The engine records your direction and judges it exactly once, at the moment the ball reaches the next tile center. Understanding that single judgment removes most wrong taps.
Bouncy Ball Physics Constants That Decide Every Bounce
A tap in Bouncy Ball only fires when the vertical velocity of the ball sits above -200. Tap during the strong part of a rise and the engine silently drops the input. Every strategy worth using starts from that one check plus three constants, all listed in the sources above.
Color Match Grid Rules Straight from the Engine
In Color Match the falling ball needs zero aiming. It drops along the vertical center line of the wheel and always strikes the top entry point, marked by the white indicator. The only question is which sector of the wheel grid sits under that marker at the moment of contact, and the engine turns tha
Basket Dunk Shot Arc Math and the Rim You Cannot Reach
The Basket Dunk shot arc is a slingshot you can compute exactly. Drag distance times 1.8 sets power, clamped between 200 and 700 pixels per second. The drag direction sets the angle, clamped to upward shots within 0.15 radians of horizontal. Gravity is a flat 980.
Drift Pro Steering Model Numbers from the Engine
Drift Pro has no steering wheel. The car slides left or slides right at speeds the engine fixes, and you pick the direction. That makes the whole game a timing model you can write down, because every number in it is constant.
Pizza Chef Order Flow Scoring Rules from the Engine
Pizza Chef looks like a speed game, but the engine runs it as an accounting system. Each serve grades your pizza with fixed rates, and two of those rates differ by exactly 10 points. Play the rates instead of the clock and the game becomes a checklist.
Hopscotch Jump Timing: The Exact Clock That Ends Your Run
Hopscotch kills you on a clock, and the clock is visible in the code. Every run ends in one of three ways, and two of them are pure timing. Read the numbers below before your next attempt, because the game punishes rhythm built on the wrong assumptions.
Merge Link Chain Rules: What a Merge Pays and When It Chains
Merge Link looks like a tapping game and scores like a chain planning game. The difference between a mediocre run and a good one is one number the engine tracks quietly, the combo multiplier. Understand the two merge paths below and your score per tap more than doubles.
Neon Maze Generation: How the Backtracker Builds Levels You Can Read
Neon Maze levels feel random until you read the generator. Every maze on every screen comes from one algorithm, and that algorithm leaves fingerprints you can play against. This article walks the generator, then turns it into rules for sliding through levels with time to spare.
Color Road Gate Logic: Spawn Odds, Color Switches, and Passing Rules
Color Road gates look like a reflex test, and the code agrees only partly. Every gate follows a spawn distribution, a passing rule, and a color switch schedule you can plan against. The players who pass 50 gates do the same arithmetic as you can, just faster.
Wall Breaker Brick Layouts: Rows, Hit Points, and Where to Aim
Wall Breaker decides your run with two numbers that move in opposite directions. Brick hit points grow every round, and your ball count grows only when a power up happens to spawn. Read the layout rules below, because the aim line alone will not save you once the numbers cross.
Nickname Generator Combination Space: 16 Styles and One Chaining Rule
Paste a transformed nick back into the generator, apply a second style, and nothing happens. Paste the same nick into a game chat and you may see rows of empty boxes. Both failures trace to specific lines in the transformation code, so we read all 16 style maps in the nickname generator and worked o
Countdown Timer Clock Drift: How Recomputed Ticks Stay Accurate
Most web countdowns subtract one second per tick. Run that counter for a week and it drifts, because every timer fires a few milliseconds late and the error accumulates into the stored value. Our countdown timer takes the other approach. It never stores a remaining value at all, and that choice remo
Gacha Habit Tracker Streak Math: Token Income Against Pull Odds
You completed all six habits in the gacha habit tracker for two weeks straight, and the collection still shows zero legendary cards. The streak is intact and the machine is not rigged. The odds in the code simply cost more than they appear to, so we computed the full exchange rate between your daily
Tinder Task List Priority Order: How Swipes Set the Ranking
You swiped twenty cards, felt productive, and the numbered to-do list came out in an order you never chose. The order is not random. The tinder task list builds its ranking from one array rule and one prepend operation, and once you know the rule you can make the list come out exactly the way you wa
AI Search Visibility Checks: What the 16 Item Score Measures
The score on our AI search visibility checker climbs when you tick boxes, and that is the whole mechanism. It never queries ChatGPT, never counts citations, and never sees your traffic. It is a self audit with fixed arithmetic, and it helps only when you know what the 16 checks weigh and what they i
Cookie Tapper Upgrade Curve, the 1.15 Cost Rule Explained
Every price in Cookie Tapper comes from one line of code. The engine charges Math.ceil of the base cost multiplied by 1.15 raised to the number you already own. Read that formula before you buy anything and the whole upgrade list turns into arithmetic.
Piano Tiles Tempo Ramp, the Speed Formula and Your Tap Budget
Piano tiles speeds up on a fixed schedule that you can compute to the tile. The engine sets speed to 280 pixels per second multiplied by a factor of 1 plus score times 4 over 280, capped at 3.5. Every tapped tile adds 4 pixels per second. Nothing about the ramp is random, so your timing plan can be
Four in a Row Win Lines, Where the Board and the AI Look
Four in a Row on this board is a 6 by 7 grid with 69 possible four-in-a-row windows. Twenty-four run horizontal, twenty-one vertical, and twelve run along each diagonal. Where you drop decides how many of those lines your disc can still join, and the engine's own AI tells you which column it fears.
Checkers Jump Rules, Forced Captures You Can Turn Into Traps
The checkers engine enforces two rules that most casual players skip. If a capture exists anywhere on your side, you must take one. If several capture chains exist, only the longest chains are legal. Read the jump code and the opponent becomes predictable, because its replies to any sacrifice are fo
Tic Tac Toe Perfect Play Against the Minimax AI
The tic tac toe engine runs minimax to the end of the game on hard, with no randomness, so hard never loses. The menu labels it Unbeatable and the code backs the label. What perfect play buys you is a guaranteed draw there and forced wins on the two lower settings, and both outcomes follow from the
