| Compare | Medplum | Oystehr |
|---|---|---|
| Verdict | Depends | Depends |
| Best for | Funded startups building custom healthcare apps | Health-tech startups building custom EHRs |
| Who it's not for | Clinics wanting an out-of-box EHR . there is no finished product | Clinics without in-house engineers |
| Privacy | HIPAA-compliant platform, but multiple 2025-2026 CVEs (SSRF, OAuth secret exposure, privilege-escalation RCE) demand prompt patching.⁷ | HIPAA compliant and ONC Health IT certified per official docs; no public vulnerability findings in sources reviewed. |
| Support quality | No support evidence in sources | No support evidence in sources reviewed |
| Public sentiment | Developers praise Medplum's programmability and FHIR foundation; non-technical buyers should expect to build, not install.³ | Independent reviews are sparse but positive, praising the developer experience, API-friendliness, and interoperability. |
| Biggest gotcha | Self-hosting the open-source core means you own uptime, HIPAA controls, and patching | Usage-based billing scales with API volume; model per-call costs before committing.15 |
