We built DevTools to fix that. It's a single, fast, ad-supported web app at https://devtools.piggyman007.com that bundles the utilities you actually reach for every day — and runs all of them 100% in your browser.
No backend. No accounts. No data ever leaves your machine.
Why DevTools Is Different
No backend. No accounts. No data ever leaves your machine.
Why DevTools Is Different
- Truly private by design. Every tool runs client-side. There is no server that receives your input — by design, not by promise. Paste a production JWT or an API response without a second thought.
- Zero friction. No login, no install, no paywall. Open the page, use the tool, close the tab.
- Genuinely fast. It's a static Next.js app served from the edge. Pages load instantly, and a ⌘K command palette plus fuzzy search get you to any tool in a couple of keystrokes.
- Dark mode first. Easy on the eyes during a late-night debugging session, with a light theme one click away.
- Works on insecure origins too. Even the copy-to-clipboard button has a fallback, so the tools keep working anywhere.
What's Inside
Encoding
- Base64 Encoder / Decoder — encode text or files to Base64 and back, including binary downloads.
- URL Encoder / Decoder — percent-encode special characters or decode encoded URL strings.
- JWT Decoder / Encoder — inspect a token's header, payload, and expiry, or build and sign new ones with HS256 / RS256.
Formatters
- JSON Formatter — beautify or minify JSON with configurable indent and live validation.
- YAML ↔ JSON — convert between YAML and JSON instantly.
- Minify & Beautify — clean up JSON, CSS, HTML, and SQL.
- JSON ↔ CSV — convert arrays to CSV (or back) with a live table preview and formula-injection protection.
Generators
- UUID Generator — generate one or many UUID v4 values with uppercase and hyphen options.
- Password Strength Checker / Generator — create strong random passwords and estimate crack times.
- Gen Lorem Ipsum! — placeholder text by words, sentences, or paragraphs.
Converters
- Timestamp Converter — Unix timestamps to human dates and back.
- Color Converter — convert between HEX, RGB, and HSL.
- Case Converter — camelCase, snake_case, kebab-case, and more.
- Number Base Converter — binary, octal, decimal, hex.
- Cron Explainer — turn cron expressions into plain English.
- Crontab Builder — build cron expressions visually.
Network
- CIDR Calculator — subnet ranges, masks, and addresses for IPv4/IPv6.
- HTTP Status Codes — a quick reference for every status code.
- URL Parser & Builder — break a URL into its parts and rebuild it.
Text
- Regex Tester — test regular expressions with live match highlighting.
- Text Diff — side-by-side comparison of two text blocks.
Cryptography
- Key Generator — RSA-OAEP key pairs or AES-GCM secret keys via the Web Crypto API.
- Hash Generator — SHA-256, SHA-512, MD5, and more, for strings or files.
- Encrypt / Decrypt — RSA-OAEP and AES-GCM encryption, all in-browser.
A Note on Security
Because these tools handle sensitive input, we hold ourselves to strict rules: cryptography uses the browser's native Web Crypto API (never Math.random for keys or tokens), CSV export neutralizes spreadsheet formula injection, and any rendered output is escaped to prevent injection. The whole point of a client-side toolbox is that you don't have to trust us with your data — so we made sure you don't have to.
And It's Growing
We're actively expanding the catalog with the most-requested utilities — a QR code generator and reader, live Markdown preview, a word and character counter, a chmod calculator, string escape/unescape, JSON-to-TypeScript, an image format converter, and more — all held to the same client-side, privacy-first standard.
