SMART on FHIR Debugger

Debug SMART on FHIR in your browser: decode JWTs, analyze scopes, and inspect smart-configuration documents. Nothing is uploaded.

• SMART on FHIR Debugger — 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.
