A Sovereign Multi-National Digital Health Operating Platform
Free · Open Source · FHIR R5 · Offline-First · Zero Vendor Lock
Everything starts and ends in GitHub.
If it is not documented, it does not exist.
If it exists, it must be automatable.
Zarish Sphere is a free, open-source, documentation-driven digital health operating platform — built to coordinate, govern, and future-proof national health programs across South and Southeast Asia.
It integrates EMR · EHR · HIS · Public Health Surveillance · ERP into a single sovereign platform — combining the best of OpenMRS, DHIS2, EWARS, Go.Data, OpenIMIS, and more. It does not replace existing systems. It makes them interoperate.

- $0 forever — only genuinely free and open-source tiers
- Offline first — full FHIR engine runs on a Raspberry Pi 5
- No vendor lock — every component is self-hostable and portable
- FHIR R5 native — all clinical data modelled as FHIR R5 resources
- GitHub governs — every decision is an RFC, every change is a PR
