Blobster use case

Decode JWTs locally before you copy or share them.

Blobster detects JWTs, decodes header and payload locally, and surfaces useful claim warnings without verifying signatures in the browser.

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

  1. Paste or open a JWT.
  2. Review the decoded preview.
  3. 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.
