PayloadBench vs jwt.io
PayloadBench decodes JWT headers and claims in a browser-local workflow. jwt.io is the most popular online JWT debugger, but it processes tokens on its server. For production tokens, this matters.

| Feature | PayloadBench | jwt.io |
|---|---|---|
| JWT processing | Browser-local header and claim decoding | Server-side. Token transmitted to jwt.io servers. |
| Production token policy | Do not paste production secrets unless your policy allows local inspection. | No — production tokens should not be sent to third-party servers. |
| Verifiable privacy | Yes — open DevTools Network tab. | No — token is sent via network request. |

Which JWT decoder should you use?
jwt.io is a great learning and debugging tool. But if you are working with production authentication tokens or security-sensitive JWTs, use a workflow that matches your security policy and can be verified in DevTools.
