About RedGreen Studio

RedGreen Studio started as a small side project: a suite of fast, lightweight developer utilities we kept reaching for ourselves — including a JSON viewer & tree editor, side-by-side diff checker, Base64 encoder, JWT debugger, and custom QR generator.

Every tool on RedGreen Studio is built offline-first and client-side. All calculations, string conversions, and data parsing run 100% locally within your browser using modern Web Workers. There are no mandatory account registrations, zero server-side data logging, and no risk of sensitive payloads, keys, or API logs ever leaving your device.

We believe essential web utilities should be blazingly fast, free of bloat, and uncompromising on data privacy. Thanks for using RedGreen Studio — we're constantly shipping new tools, and feedback is always welcome!

Why Client-Side Matters
Every tool runs entirely within your browser using local execution logic. By keeping operations offline-first, your data stays strictly on your machine — ensuring ultra-fast execution times with maximum privacy compliance. No logins, no tracking scripts, and no server roundtrips. Just clean, reliable utilities when you need them.
