what is [devbox]?


devbox is a collection of tools built by developers who got tired of sites that require login to format json, questionable online converters, and heavyweight apps for tiny everyday tasks.

every tool runs entirely in your browser. your data never leaves your machine. we don't know what you paste here and we don't care.

we believe developer tools should be fast, offline-capable, honest, and free. not "free" as in we track everything you do. actually free.

if a tool needs a server (like ipynb → pdf), we'll tell you clearly. everything else is designed to stay client-side.

we're open source. if you find a bug, have an idea, or want to contribute a tool, open an issue ↗
