SMART on FHIR Token Inspector

Decode SMART on FHIR access tokens and id_tokens in your browser: claims, expiry, scope and fhirUser. Signature verification only with a JWKS you provide.

• SMART on FHIR Token Inspector — part of the free FHIR Toolbox library.
• Runs entirely in your browser: your FHIR data is never uploaded to a server.

FHIR Toolbox is a free, privacy-first collection of HL7 FHIR utilities by Omindra Labs. Every tool performs zero-server processing — your health data never leaves your device.
