TokenlyDecode & verify tokens offline

Tokenly decodes any JSON Web Token in an instant and shows you exactly what is inside — header, payload, and every claim — without a single byte leaving your device.

Built for developers tired of pasting production tokens into random websites, it does the whole job locally. Paste a token and it splits out the header and payload, pretty-prints the JSON, and translates the standard claims into plain language: when the token was issued, when it expires, who it is for, and whether it is already stale.

WHAT MAKES JWTDECODER DIFFERENT

• Instant local decode
  Paste a token and the header and payload are split out and pretty-printed right away.
• Claims in plain language
  Standard claims such as iss, aud, exp, and iat are translated into a readable summary instead of raw JSON.
• Timestamps you can actually read
  Expiry and issued-at times are rendered as dates, so an expired token is obvious at a glance.
• Recent-token history
  Everything you decoded stays one tap away when you need to compare or revisit it.
• A signature toolkit that stays local (Pro)
  Verify HS256/384/512 signatures with your own secret, and build and sign custom test tokens for your own APIs.
• Nothing is uploaded
  No network calls, no accounts, no analytics, no third-party SDKs — your tokens, secrets, and history never leave your iPhone.

WHO IS JWTDECODER FOR?

• Developers tired of pasting production tokens into random websites
• API and backend engineers debugging auth flows
• Anyone checking when a token expires and who it was issued for
• Teams who need token work to stay off the network entirely
