Hey PH! 👋 I built DevUtils because every time I needed a quick Base64 decode or a JWT inspection, I ended up on sites that: - Required signup for basic features - Sent my inputs to some server I don't control - Were slow and clunky - Or had a dozen popups before I could copy the result I just wanted a fast, clean, dark-themed toolkit that processes everything in my browser. So I built it. What's inside (11 tools, all 100% client-side): - JSON Formatter & Validator - Base64 / URL / HTML Encoder-Decoder - UUID Generator (with bulk mode) - JWT Decoder - Unix Timestamp Converter - Hash Generator (MD5, SHA-1, SHA-256, SHA-512) - Password Generator - CSS Formatter / Minifier - Regex Tester Built with React 18 + TypeScript + Vite. No backend, no API calls, no server processing your sensitive strings. Your JWT tokens, passwords, and hashes never leave your device. It's free. No signup required. I'd love your honest feedback — what tool am I missing? What's broken? What would make this your go-to tab? Cheers!
