Community
Code without contributors is code that will be abandoned. We build the contributor community first, then the work the community can sustain.
Open Source Harbor
A community building open-source health infrastructure that lasts.
Maintained with care. Shared without condition.

- HL7
- SMART on FHIR

THE PROBLEM
Health systems are told to adopt open-source tools. The repositories they find often have no documentation, no governance, no contributor community, and no clear path from code to deployment. Tools that started with promise get abandoned when the original grant ends. Health organizations are left with software they cannot maintain, extend, or trust.
Open source in global health often means free to download, expensive to fail with.
Open Source Harbor exists to do this differently. Health systems deserve open-source infrastructure with active maintainers, working governance, accessible documentation, and a community that persists across funding cycles.
PRINCIPLES
Governance
Decisions about direction, security, integration, and adoption need clear processes. We document governance before we ship.
Standards
Interoperability is non-negotiable for health technology. FHIR R4, OMOP, HL7, and SMART on FHIR are the spine of everything we work on.
OUR APPROACH
Platforms in our practice
We do not reinvent what already exists. The open-source health technology ecosystem includes mature, capable platforms maintained by global communities. Open Source Harbor practitioners implement, integrate, and contribute to that ecosystem.

Visit project →When existing platforms meet a need, we deploy and contribute back. When something is missing, we build it as an extension to an existing platform community rather than as a parallel product.
The OSH community works with FHIR R4 as the common data standard. Contributions and integrations across platforms in our practice share this standard, making outputs interoperable with existing health technology ecosystems.
GOVERNANCE
A program of the Adloris Foundation.
Open Source Harbor is a program of the Adloris Foundation, a 501(c)(3) based in the United States. The Foundation provides institutional resilience, fiscal stewardship, and grant eligibility. Day-to-day technical work is coordinated by a transatlantic contributor community. Work is built on open standards and shared without condition.

CONTRIBUTE
Build with us.
Developers
Contribute to our open-source projects. Repositories include contributor onboarding guides and tagged first issues.
Health Organizations
Deploy open-source health infrastructure with implementation support. We work with FQHCs, community health systems, public health departments, and organizations serving underserved populations.
Funders
Sustainable open-source health infrastructure depends on funders who understand that maintenance, governance, and community are as important as initial development. NSF POSE, NIH, USAID, RWJF, and Sloan are among the active pathways for this work.
