JWT Time Machine
Decode a JWT and see its issued/valid/expiry claims plotted on an actual timeline.
Paste a JWT
Decodes claims and timing only — this never checks or requires a signature.
Understand JWT Time Machine
What this tool helps you understand
Paste a JWT and instead of a wall of decoded JSON, see iat, nbf, and exp laid out on a timeline against right now — was this token ever valid, is it valid now, and exactly when does it die.
When to use it
Use JWT Time Machine when engineering, backend, and security work raises questions about jwt decoder, token expiry, and jwt debugger and you need a concrete view before making the next move.
How to read the result
Read each finding as a diagnostic signal, then confirm it against the contract, system, file, or production context you actually control.
Assumptions and limits
JWT Time Machine decodes time-related claims for inspection. It does not verify the token signature, issuer authenticity, revocation state, permissions, or server-side acceptance.
