DevUtils
25 free dev tools that run in your browser. No signup.
A suite of 21 essential utilities for developers — JSON formatter, Base64, URL encoder, UUID generator, JWT decoder, CSS formatter, regex tester, hash generator, password generator, timestamp converter, HTML encoder. No signup. No server. Dark theme.
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!
