Blobster use case
Decode JWTs locally before sharing claims.
Blobster decodes the header and payload in your browser and shows claim timing warnings. It does not verify signatures.
Where Blobster fits.
Decode header and payload in the browser.
Show `exp`, `iat` and `nbf` as readable times where present.
Warn on expired tokens and `alg: none` cases.
Typical workflow.
Use Blobster as a fast local inspection step before copying, sharing or acting on data.
- 01 Paste or open a JWT
- 02 Review the decoded header and payload
- 03 Copy only the claim or redacted output you need
Use the local viewer, not a paste site.
Blobster is built for quick inspection of structured developer data that may contain tokens, customer payloads, headers, internal URLs or support evidence.
