Medblocks vs Rhapsody
How Medblocks compares to Rhapsody and the integration engines, across surfaces, patient state, and pricing.
Rhapsody is a healthcare integration engine. It sits in the integration-engines circle of the healthcare integration landscape, alongside Mirth Connect, Cloverleaf, Iguana, and WSO2. These tools are infrastructure: a provider IT team deploys them inside its own walls to route messages between the systems it already runs, with a lot of custom mapping and configuration. They are routing layers, not a system of record, so they do not maintain patient state.
Quick verdict
Choose an interface engine if you are a provider IT team wiring your own systems together. Engines are excellent at HL7v2 transformation and routing between the applications you already operate, and within that job they are battle-tested.
Choose Medblocks if you are building a digital health product that needs to reach many external organizations through modern FHIR surfaces, with a maintained patient record and a data layer on top. An engine moves messages; Medblocks gives you the surfaces, the record, and normalized data, not just a pipe.

- Medblocks brokered access: we provide extensive written guidance and one-to-one support on contracting with an organization and getting your own credentials installed. We don't do it on your behalf with our credentials.
- Medblocks HL7v2 interfacing: supported over HTTP with SMART Backend authentication, which major EHRs like Epic support natively.
- Export to FHIR CDR (interface engines): engines route messages and keep no longitudinal patient record, with no native FHIR conversion, so reaching a FHIR CDR takes heavy custom mapping.
- Rhapsody pricing: based on the AWS Marketplace listing for Rhapsody as a Service.

What interface engines do well
Engines are powerful routers. Built for provider IT teams, they move messages between the systems an organization already operates and handle HL7v2 transformation and routing very well. For internal interfacing inside one organization, they are the proven tool.
Each has its own flavor, from Rhapsody and Cloverleaf at the enterprise end to Iguana’s scripting model and WSO2’s open-source platform, but the job is the same: route and transform messages between known systems.
Where Medblocks goes further
They are a different tool for a different buyer. An engine is deployed inside one organization to connect its own systems; it is not built for a digital health product to reach many external organizations. Engines center on legacy HL7v2 rather than the modern FHIR surfaces, and they route messages without maintaining patient state, deduplicating, or modeling the data.
Medblocks gives you the modern surfaces, a maintained patient record, and the data layer, not just a pipe between systems. Reaching a FHIR CDR or a normalized model from an engine means heavy custom mapping that you build and maintain.
Pricing
Engine pricing is mostly enterprise and license-based, rarely published. Rhapsody runs around $50,000 per year and up, Mirth (proprietary since v4.6), Cloverleaf, and Iguana are quote-based, and WSO2 is open source with paid subscriptions. Every option prices the engine itself, before the custom integration work, the external surfaces, and the data layer you would still need to build.
Using them together
If a provider you work with already runs an engine, you do not have to replace it. Medblocks can receive HL7v2 from the engine and take it from there, deduplicating and normalizing it alongside your other sources into one patient record, while the engine keeps doing the internal routing it is good at.
