About RedGreen Studio

RedGreen Studio started as a small side project: a handful of developer utilities we kept reaching for ourselves — a JSON viewer, a diff checker — built to be fast, free, and completely private.

Every tool we ship runs entirely in your browser. There are no accounts required, no tracking of your data, and nothing you paste or upload is ever sent to a server unless you explicitly choose to save it with a Pro plan.

We're a tiny, independent team who believes good tools should be simple, honest about what they do, and respectful of your data. Thanks for using what we've built — feedback is always welcome.
