Compare Tentaco vs jwt.io: local JWT decode and inspect without sending tokens to Auth0 infrastructure.
jwt.io by Auth0 is the reference JWT debugger — paste a token and see header, payload and signature hints. Tokens are processed in the browser but the site is tied to Auth0 branding and encourages their ecosystem.
Tentaco JWT Decoder runs fully local for standard decode — better when debugging production session tokens you must not leak to third parties.
| Funzione | Tentaco | jwt.io |
|---|---|---|
| Token leaves device | No for decode | Browser-only but Auth0 site |
| Signature verify | Inspect claims | HMAC/RSA hints |
| Account | None | None |
| Vendor lock-in | Independent | Auth0 ecosystem |
| Price | Free | Free |
Use Tentaco to inspect JWTs without Auth0 association. jwt.io remains useful for signature algorithm docs.
