I just finished building 18 free dev tools that run entirely in your browser — would love your feedback

I finally shipped something I've been working on for a while and I'm pretty excited about it. I got tired of landing on sketchy sites full of ads every time I needed to format some JSON or decode a JWT. So I built something cleaner. It's called DevToolKit — 18 developer tools, all free, all running 100% client-side in your browser. No accounts, no installs, just open and use. JSON Formatter & Validator JSON Converter (to CSV, XML, YAML, SQL) JSON Schema Validator JSON Diff CSV Viewer Data to Excel Base64 Encode & Decode Image to Base64 & Back JWT Encode & Decode Hash Generator (MD5, SHA-256, SHA-512) UUID Generator (v1, v4, v7) Fake Data Generator Regex Tester Word & Character Counter and more Your data never leaves your browser. The part I'm most proud of: you can load the page, turn off your wifi, and every single tool keeps working. No server, no API calls, nothing. Try it — open a tool, disconnect, paste your data. It just works. 🔗 [ https://www.devtool-kit.com ] Would love to hear
