Hey DEV community! I built BeginThings — a collection of 20+ free, browser-based tools for developers, designers, and freelancers. Everything runs client-side, no data leaves your browser.
Why I Built This
I was tired of tools that require sign-ups, track your data, or hit you with paywalls after 3 uses. So I built single-page HTML tools that work instantly — no backend, no cookies, no BS.
Developer Tools
- JSON Formatter & Validator — Format, validate, minify, convert JSON to CSV, tree viewer
- Base64 Encoder/Decoder — Encode/decode text, files to Base64, image preview from data URIs
- Password Generator — Cryptographic random passwords, passphrases, strength checker, bulk generation
- Lorem Ipsum Generator — Classic lorem ipsum, hipster ipsum, dummy data generator, name generator
- Color Picker — HEX/RGB/HSL converter, palette generator, contrast checker
Text & Content Tools
- Word Counter — Real-time word/character count, reading time, text analyzer, find & replace, case converter
- QR Code Generator — URL/text/vCard/WiFi QR codes, custom colors, batch generation, scanner
Image Tools
- Image Compressor — Compress, resize, convert images. All processing in-browser via Canvas API
Financial Calculators

- Unit Converter — 10+ categories, 200+ units
- And more at beginthings.com
Tech Stack
Each tool is a single self-contained HTML file — all CSS and JS inline. No frameworks, no build step, no npm. Just vanilla HTML/CSS/JS that works everywhere.
- Dark theme (#0a0a0a background, cyan accents)
- Mobile responsive
- JSON-LD structured data for SEO
- Works offline once loaded
