About CodeBench

CodeBench is a free, browser-based developer toolbox built for programmers, designers and students. It started as a simple idea — why do developers have to visit ten different websites to do ten simple tasks? Why are so many of those sites slow, cluttered with ads, or hidden behind sign-up walls?

CodeBench brings the most commonly needed developer utilities into one clean, fast, always-free workspace. No login. No installs. No paywalls. Just open a tool and get to work.

Our Principles

Fast
Every tool loads instantly. No heavy frameworks on the client side, no waiting for servers to respond. Just open and use.
🔒
Private
All processing happens in your browser. The code you paste, the passwords you generate, the tokens you decode — none of it ever leaves your device.
🆓
Free Forever
CodeBench will always have a free tier. Developer tools should be accessible to everyone — students, freelancers and professionals alike.
🎯
No Bloat
No sign-up popups. No cookie consent walls every 5 seconds. No dark patterns. Just tools that work.
