Privacy-first toolkit for developers. JSON formatter, JWT decoder, SQL formatter, regex tester, password generator, image compressor, OCR, RSA key generator, and 40+ more — all run 100% in your browser.
No backend. No account. No ads. Your data never leaves your device.
Some tools include an optional on-device AI (Chrome's Gemini Nano) that explains JSON, SQL, and JWTs — zero API calls.
