I Built 480+ Free Online Tools for Developers (And They're Actually Useful)

I Built 480+ Free Online Tools for Developers (And They're Actually Useful) As a developer, I constantly find myself reaching for online tools — JSON formatters, base64 encoders, color pickers, regex testers. You know the drill. You Google something, click a random result, and end up on a site plastered with ads and popups. So I decided to build my own. One year later, ToolSnap has grown into a collection of 480+ free online tools — no sign-up, no ads, no nonsense. What's Inside? 🔧 Developer Tools JSON Formatter & Validator — Paste messy JSON, get beautifully formatted output Base64 Encoder/Decoder — Encode and decode text, files, and URLs JWT Decoder — Inspect JWT tokens without sending them anywhere Regex Tester — Real-time regex testing with match highlighting Hash Generator — MD5, SHA-1, SHA-256, SHA-512 🎨 Design Tools Color Picker — Pick any color, get HEX, RGB, HSL values instantly Contrast Checker — WCAG AA/AAA compliance checker CSS Gradient Generator — Visual gradient builder
