About CodeBoxTools
Free developer tools that respect your privacy. Every tool runs in your browser — your data never touches a server.
Why CodeBoxTools Exists
You know the drill. You need to decode a Base64 string, generate a UUID, or check a diff. You search for a quick online tool and land on a site plastered with ads, pop-ups, and cookie banners — wondering the whole time if your data is being logged on some server halfway around the world.
CodeBoxTools was built to fix that. Every tool on this site runs entirely in your browser using JavaScript. Nothing is uploaded. Nothing is stored. Nothing is tracked. You paste your data, get your result, and move on.
No accounts. No paywalls. No dark patterns. Just fast, private utilities that work the way developer tools should.
Whether you are debugging a JWT at 2 AM, converting timestamps during a deploy, or diffing config files before a release, CodeBoxTools is designed to be the tab you keep open. We started with 61 tools across conversion, encoding, generators, and comparison categories — and we are adding more based on what developers actually need.
Our Principles
Privacy First
All processing happens client-side in your browser. Your data is never sent to any server, never logged, never stored. We use no tracking cookies and no analytics that identify you.
No Barriers
No signup, no email gates, no "free tier" limits. Every tool is completely free. Open the page, use the tool, done. That is how developer utilities should work.
Speed Matters
Static HTML with minimal JavaScript. Tools are interactive the moment the page loads. Built with Astro for maximum performance and near-instant page transitions.
Transparent Monetization
Some pages include clearly labeled affiliate links to services developers actually use. These links never share your tool data with anyone. That is how we keep the lights on without compromising your experience.
By the Numbers
Built By
An Independent Developer
Built by a software developer who got tired of pasting sensitive data into tools they did not trust. Every tool here is one they use themselves.
