Open Integration Engine (OIE) is a vendor-neutral, open-source healthcare integration engine designed for speed, scalability, and seamless interoperability. As a mature and proven platform, OIE is trusted by thousands of organizations worldwide to manage critical data exchange.
OIE is a community-driven fork of Mirth® Connect, established to preserve the open-source mission after Mirth transitioned to a proprietary licensing model starting with version 4.6.0.
Meditecs is a proud sponsor and contributor to OIE. We utilize OIE as the foundation for our own Meditecs Smart Connect integration platform, ensuring our clients benefit from a stable, future-proof, and truly open ecosystem.
OIE is fully compatible with existing Mirth® Connect channels and configurations created in versions prior to 4.6.0, allowing for a straightforward migration.
