About

Rich Dev Tools is a free collection of browser-based utilities built for developers who value speed, privacy, and simplicity.

Why We Built This

Every week developers google the same things - 'generate UUID online', 'encode base64', 'format JSON'. Most results require sending your data to a server. We built Rich Dev Tools differently: everything runs in your browser, fast and without friction.

Privacy by Design

All tools run entirely in your browser. We do not collect, store, or transmit any data you enter. No accounts, no tracking beyond basic analytics, free.

No server processing
No account needed

Over 25 tools across generators, encoders, converters, and text utilities. UUID v1-v7, password generator, hash/HMAC, Base64, JWT, JSON formatter, YAML converter, regex tester, diff, crontab editor, and more.
