Harmony Proxy

A secure, pluggable proxy for data meshes, with first-class healthcare support (FHIR, DICOM/DICOMweb, JMIX).

Overview​

Harmony Proxy is an extensible data mesh proxy/gateway for heterogeneous systems. It routes requests through configurable endpoints, middleware, and services/backends to connect systems securely.

Who Is This For?​

  • Platform teams building data meshes or integration hubs (healthcare and beyond)
  • Developers integrating HTTP/JSON services and healthcare protocols (FHIR, DICOM/DICOMweb)
  • Operators who need auditable, configurable request/response pipelines

Architecture​

Harmony uses a pipeline architecture:

  1. Endpoints - Define public-facing routes and protocols
  2. Middleware - Process and transform requests/responses in order
  3. Backends - Perform the actual work (HTTP calls, DICOM operations, etc.)

All components are configured via TOML files and can be hot-reloaded.

Status​

Harmony Proxy is under active development. For more information, visit harmonyproxy.com.
