Most developer tools either specialize in one thing or require you to trust a server with your code. CODEBENCH gives you 80+ tools — JSON formatter, regex tester, JWT decoder, markdown editor, and more — all running 100% in your browser. No backend. No data uploads. No signup. Your code never leaves your machine. Built with Next.js and designed for privacy by architecture, not by policy. Every tool works offline once loaded. Stop pasting sensitive code into random websites.

Learns your product. Thinks through UX

Hey! I made CODEBENCH. This started from a pretty simple frustration — I had like 30 bookmarks for random dev tools. One for JSON, one for JWT, one for regex... you know how it goes. And honestly, half of them felt sketchy. I never loved pasting production configs into some unknown server. So I thought, why not just build all of them in one place, running completely in the browser? No server, no uploads, nothing leaves your machine. That's literally how CODEBENCH works — there's no backend at all. Right now there are 80+ tools in there. JSON formatting, regex testing, JWT decoding, markdown tables, cron parsing, base64, hashing... I keep adding whatever I find myself needing during work. Would love to know what tools you use daily that you wish were better. Always looking for what to build next!
