About Medplum

Medplum is a commercial open-source FHIR platform written in TypeScript. It bundles a FHIR R4 server, identity, SMART on FHIR, workflow automation, and a React component library — targeted at application developers rather than hospital IT.

Scores by profile

• Bulk Data kickoff surface: 83% (5/6) — MUST 2/2 · SHOULD 1/2 · MAY 2/2
• FHIR R4 base spec: 91% (21/23) — MUST 6/7 · SHOULD 9/9 · MAY 6/7

Each cell links to the profile-level scoreboard comparing Medplum against every other tested server.

Methodology

Tests are authored as FHIR R4 TestScript Resources and run by an open-source executor against a fresh Docker deployment of each server. We deliberately don't compute a composite number — read the methodology for the reasoning.
