Behind-the-firewall integration made simple
API Gateway is the open-source foundation that makes diverse data systems interoperable. Deploy as a lightweight container to connect legacy healthcare systems with modern APIs, enabling secure data exchange between organisations.
Secure by Design
Built-in authentication middleware, encrypted data exchange, and compliance-ready audit trails for regulated industries.
Healthcare Native
Purpose-built for EMR-PACS integration, FHIR-HL7 gateway functionality, and connecting legacy healthcare systems.
Extensible Architecture
Pluggable data transformations, custom connectors, and extensible middleware for specialised protocols.
Modern Protocol Support
HTTP/3 (QUIC) for low-latency connectivity and Data Mesh for secure cross-org networking.
FHIR
HL7
DICOM
REST API
SECURE TUNNEL
API Gateway
How it Works
Deploy lightweight gateways in your infrastructure, connect them to Runbeam for centralised management, and route data through secure transformations across any protocol or network boundary.
1
Deploy as Containers
Pull the Harmony image and deploy in Docker, Kubernetes, or bare metal. Each instance runs independently behind your firewall with no external access required.
2
Connect to Runbeam
Register your gateways with the Runbeam control plane. Centralised configuration management, policy enforcement, and monitoring across all your deployed instances.
3
Route and Transform
Define data flows in your pipelines: ingest from legacy systems, transform between protocols (FHIR, HL7, DICOM, REST), and route to modern APIs with audit trails and compliance logging.
Core Capabilities
Four pillars of secure data connectivity
Data Transformations
Translate between FHIR, HL7, DICOM, and modern JSON APIs in real-time. Bridge healthcare protocols with REST API integration and GraphQL federation.
Authentication Middleware
Enforce modern authentication policies with OAuth 2.0, JWT, and API key management. Secure tunnelling without modifying existing systems.
HTTP/3 (QUIC) Support
Modern protocol with multiplexed streams, faster connection setup, and superior performance on unreliable networks. Mandatory TLS 1.3 encryption built-in.
Data Mesh Networking
JWT-based mesh connectivity for secure cross-organisation data exchange. Connect distributed proxies without VPN complexity.
Deploy Anywhere
Run wherever your infrastructure lives
Harmony Proxy runs as a lightweight container, giving you complete control over deployment. Install on-premises, in the cloud, or at the edge—wherever your data needs to be processed.
Docker
Pull and run with a single command. Compose with existing services or deploy standalone.
Kubernetes
Deploy with Helm charts. Scale horizontally and integrate with existing cluster infrastructure.
Bare Metal
Install directly on Linux, macOS, or Windows servers for maximum performance.
Edge Computing
Deploy at clinic sites or remote facilities for local data processing with minimal latency.
Quick Start with Docker Compose
curl -O https://runbeam.io/downloads/harmony-docker-compose.ymlcurl -O https://runbeam.io/downloads/harmony-config.tomldocker compose -f harmony-docker-compose.yml up -dThis pulls the pre-built multi-arch image and starts Harmony with sensible defaults. Works on AMD64 and ARM64 systems.View full installation guide
MIT Licensed
Truly open source
Harmony Proxy is released under the permissive MIT License, giving you complete freedom to use, modify, and distribute the software—commercially or privately.
- Full source code access: Inspect, audit, and understand exactly how your data flows
- No vendor lock-in: Own your integration layer without licensing restrictions
- Commercial use allowed: Build products and services on top of Harmony Proxy
- Community contributions: Submit bug fixes, features, and improvements
Why open source matters
In regulated industries like healthcare, transparency isn't optional—it's essential. Open source enables security audits, regulatory compliance, and community-driven security improvements.
When you control the code, you control your compliance posture, security updates, and integration roadmap. No waiting for vendor release cycles or feature requests.
Community Driven
Built by developers, for developers
API Gateway represents a fundamental shift in data connectivity. Instead of building point-to-point integrations that become technical debt, we're creating a flexible, secure, and maintainable foundation for data interoperability.
