What is the FHIR Resource Generator?

The FHIR Resource Generator produces synthetic FHIR R4 JSON for development, QA, and interface testing. Every resource is deterministic by seed — the same seed always generates the same output, so you can reproduce test scenarios exactly.

Supported Resource Types

Patient (basic / full), Observation, Encounter (inpatient / outpatient / emergency)
Condition, Procedure, MedicationRequest, Immunization, AllergyIntolerance
DiagnosticReport, Bundle (transaction / document / message / searchset / collection)
