What it does

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.
