Build on a legacy and be ready for what’s next. Looking for a Mirth Connect alternative? Learn why tech teams are replacing Mirth with Rhapsody for scalable, secure interoperability.
With Mirth Connect sunsetting its open-source model and introducing a commercial licensing structure, technical teams are reassessing the long-term viability of their integration infrastructure. This post outlines why many are choosing to transition to Rhapsody for scale, stability, and support.
For nearly two decades, Mirth Connect was a trusted healthcare integration engine for connecting systems quickly, especially for teams working with limited budgets. Its open-source foundation, strong developer community, and rapid time to value made it a go-to engine for health tech vendors, HIEs, and providers looking to move quickly and cost-effectively.
Mirth helped many organizations get started. But now, as integration needs scale and the product evolves, teams are evaluating whether it’s still the right fit.
Evaluating a Mirth Connect alternative? What to consider
With the release of Mirth Connect 4.6, the solution is no longer open source. Under NextGen Mirth licensing, it now operates under a commercial licensing model, with key features gated behind enterprise packages. Managed services are limited to U.S.-based customers, and many of the original developers are no longer maintaining the core code—whether in the commercial version or the forks.
This shift raises important considerations:
- How do we scale without replicating and maintaining dozens of integration engine instances?
- What’s the cost of stitching together third-party monitoring, alerting, and version control?
- Can our infrastructure handle rapid growth or customer onboarding?
- Is our integration foundation built for long-term reliability, performance, and support?
- Should we continue with commercial licensing or explore an open source Mirth replacement?
- Are we risking stability by relying on a forked Mirth Connect deployment?
Why Rhapsody is the next step
The Rhapsody graphical UI, reusable templates, and drag-and-drop interface design reduce time spent writing and maintaining custom code. For teams who prefer scripting, we also offer support for both modern JavaScript and the older Rhino version used in Mirth—making it easy to bring over existing logic, Global Scripts, and Code Templates.
Easier to use and maintain
Rhapsody’s graphical UI, drag-and-drop interface design, and reusable templates reduce the need for advanced scripting. It’s faster for engineers and more maintainable for teams.
Built for scale
With Locker and Container architecture, Rhapsody enables organizations to run thousands of interfaces from a single instance. This helps reduce infrastructure footprint, simplifies monitoring, and lowers total cost of ownership as you grow.
Flexible deployment
Rhapsody can be deployed in your environment, in the cloud, or fully managed by us. Options like Rhapsody as SaaS and Envoy iPaaS offer multi-region availability and reduce the internal lift of managing integration infrastructure.
Observability and support included
Unlike open-source Mirth, Rhapsody includes granular monitoring, alerting, audit logging, and API access as part of the core platform—no bolt-ons required. Our 24/7 global support team is available across North America, EMEA, LATAM, and APAC.
Respecting the past, enabling the future
The operational complexity of managing multiple engine instances, coupled with the growing pressure to deliver secure, scalable, and compliant data exchange, has pushed many organizations to explore alternatives.
We’ve helped healthcare organizations migrate to Rhapsody not just to replace Mirth, but to consolidate environments, speed up onboarding, and future-proof their integration strategy.
Take Qventus, for example. The team transitioned from 20 separate Mirth instances to a single Rhapsody deployment. This Mirth replacement led to a 10x performance improvement, a reduction in onboarding time by more than 50%, and a significant decrease in infrastructure cost per customer – proving the business case for moving beyond Mirth Connect.
