JWT Debugger & Inspector

Stop pasting auth tokens into random websites. Inspect your JWTs locally and keep your session secrets where they belong: on your machine.

Secure Debugging

Authentication tokens are highly sensitive. Omnitool decodes JWT segments natively, allowing you to inspect expiration dates, roles, and headers without ever hitting a network.
