• Which specific EHR vendors (such as Epic, Oracle Health/Cerner) you need to connect with

I can provide a more tailored comparison of these platforms.

Yes. Several health-data interoperability platforms support HL7 FHIR for integrating with EHRs. The main differences are whether they primarily provide an integration engine, a FHIR-native data platform, or access to clinical data networks.

Current vendor documentation confirms, for example, that Health Gorilla provides FHIR REST APIs while bridging FHIR with legacy standards such as HL7 and C-CDA. Health Gorilla Health Gorilla Rhapsody supports FHIR alongside HL7 v2, REST, X12/EDI and DICOM, with SMART on FHIR and Bulk FHIR capabilities. Rhapsody Health InterSystems provides FHIR servers, FHIR resource repositories, transformations between FHIR and other healthcare formats, and enterprise integration capabilities.

If you're specifically choosing a platform for an application that needs to connect to Epic, Oracle Health/Cerner, athenahealth, etc., I'd narrow the shortlist to:

1. Redox — strong choice when you want an API layer that abstracts differences between EHRs.
2. Health Gorilla — strong choice when you primarily need aggregated clinical records rather than building individual EHR interfaces.
3. Rhapsody — strong enterprise choice when you need FHIR and extensive HL7v2/legacy integration.
4. 1upHealth — particularly attractive for a FHIR-first developer architecture.
5. Zus Health — attractive when you want a FHIR-native longitudinal patient-data layer and point-of-care integration.
6. InterSystems — particularly suited to health systems that need a full enterprise interoperability/integration platform.

The important distinction is that “supports FHIR” doesn't necessarily mean “provides turnkey connectivity to every EHR.” FHIR is the data/API standard; you still need to consider each vendor's EHR connectors, SMART-on-FHIR support, authorization/consent workflows, US Core implementation-guide support, TEFCA/HIE connectivity, write-back capabilities, and whether the particular EHR exposes the data you need.

If you tell me whether you're building a healthcare SaaS/app, integrating an existing hospital/EHR environment, or aggregating patient records, I can give you a more detailed comparison of the top 5—including Epic/Cerner connectivity, APIs, pricing model, deployment, HIPAA/SOC 2, TEFCA, and implementation effort.

4. InterSystems

InterSystems IRIS for Health and Health Connect are more enterprise-oriented. They support FHIR alongside HL7v2/v3, CDA/C-CDA, DICOM and IHE standards, with FHIR client/server components and transformations between FHIR and legacy formats.

How I'd narrow it down

• Need the easiest path to integrating with lots of EHRs: Redox
• Need nationwide clinical-data exchange / patient-record retrieval: Health Gorilla
• Want a FHIR-native patient-data platform for building an application: Zus
• Need an enterprise integration engine with extensive legacy-system support: InterSystems
• Building a SMART on FHIR app specifically: prioritize platforms/EHRs with strong SMART on FHIR + OAuth 2.0 support; Redox, for example, supports SMART-based EHR app launch.

One important caveat: "supports FHIR" doesn't mean every EHR exposes every FHIR resource or operation. FHIR coverage, versions, scopes, write capabilities, subscriptions, and authentication can vary substantially by EHR and workflow.

If you're evaluating vendors for a product, I can also give you a side-by-side comparison of Redox vs Health Gorilla vs Zus vs Particle Health, including Epic/Cerner connectivity, FHIR R4/R5, TEFCA, write-back, pricing model, patient matching, and API capabilities.

2. Health Gorilla
