JamBridge vs Mirth Connect
Mirth Connect (now NextGen Connect) is a free, open source HL7v2 interface engine. It is the most widely deployed free HL7v2 tool globally, especially in public sector and resource-constrained environments.
Quick verdict
Choose Mirth Connect if budget is zero, you have JavaScript/Groovy developers who can build and maintain custom transformers, and your interoperability needs are point-to-point HL7v2 routing between existing systems.
Choose JamBridge if you are building a national or chain HIE on FHIR R4, need production-grade consent enforcement and patient identity, and want a supported, auditable pipeline with a commercial SLA.

Mirth is a router; JamBridge is a clinical engine
Mirth Connect routes messages. It does not understand what an ADT A01 means clinically. Every transformation, every identity lookup, every consent check has to be implemented as a custom JavaScript transformer in Mirth — and maintained across Mirth upgrades.
JamBridge implements the clinical meaning of each HL7v2 message type and applies a fixed, auditable pipeline. The result is less flexibility but more correctness — and far less custom code to maintain.
Using them together
Mirth Connect and JamBridge can coexist. A common pattern during migration: Mirth handles legacy point-to-point interfaces that are not worth migrating, while JamBridge handles all new FHIR-native integrations. Traffic is split at the network level by destination IP or port range.
