About
NIXX/DEV
A curated collection of free, easy-to-use online tools for developers, designers, and data professionals.
nixx.dev started as a personal toolkit — a place to collect the small utilities that kept coming up in day-to-day development work. Over time it grew into something more deliberate: a site built around the idea that the best tools are the ones that just work.
No accounts. No paywalls on the core features. No unnecessary complexity. From JSON formatting and JWT decoding to image compression and QR code generation, every tool is crafted to solve a specific problem quickly and get out of your way.
Fast by default
Every tool loads instantly and runs in your browser. No waiting for servers, no spinning loaders.
Private by design
Your data never leaves your device. All processing happens locally — nothing is stored or transmitted.
Built for real work
Each tool is designed around a genuine workflow need, not a checkbox. If it does not solve a real problem, it does not ship.
