Fhirforge

Health-tech teams may spend months assembling realistic FHIR test data and prior-authorization scenarios before they can exercise product behavior. The supplied research confirms a free synthetic-data generator, free conformance tooling, static data packs and adjacent reference-data APIs, but found no directly matching hosted, configurable sandbox.

Fhirforge would provide versioned synthetic personas and FHIR R4 records, plus scenarios for named implementation guides and expected responses. Teams could clone a dataset, apply controlled mutations, run a system under test and compare actual results with an explicit oracle. Every result would preserve generator, seed, profile, guide version, validator version and execution evidence.

Synthetic is not automatically safe. Generator inputs, copied examples, free text, rare combinations and customer-added records can introduce sensitive or identifying data. The service must prohibit production patient data by default, scan and quarantine uploads, isolate tenants and make provenance visible. Likewise, a validator PASS is bounded to the exact fixture, profile and tool version; it is not certification, interoperability, regulatory compliance or clinical correctness.

The buyer hypothesis is a health-tech engineering or interoperability team that lacks reusable test infrastructure. The supplied evidence does not establish exact role, budget or current spend. A pilot should cover one implementation guide and a small scenario suite, then prove reproducibility, defect discovery and trust in the oracle before promising a broad corpus.

A health-tech engineering, integration or quality team that needs repeatable FHIR scenarios but cannot justify maintaining its own generator, implementation-guide corpus and validator matrix.
