Tools for Developers
Format JSON, encode Base64, build color palettes, clean up text — the small jobs you do every day, done in one fast page. Nothing you paste ever leaves your device.
No tools match that search. Try "json", "base64" or "color".
> About DevKit
DevKit is a small, focused toolkit for developers and designers. Every tool runs entirely in your browser — your JSON, code snippets and text are never uploaded to a server, so you can use DevKit on real project data with confidence.
The set is deliberately tight: the nine utilities developers reach for most — formatting and validating JSON, encoding and decoding Base64, HTML entities and URLs, counting and cleaning text, and working with color. No accounts, no ads in your way, no waiting on a server round-trip. Open a tool, paste, get your answer, copy it out.
