Mere Medical
Self-hosted personal health record (PHR) that aggregates and syncs medical records from multiple patient portals into a local, privacy-first web app.

Mere Medical is a self-hosted personal health record (PHR) web application that aggregates and syncs medical records from multiple patient portals into a single timeline and summary interface. It is designed to be local-first and privacy-focused so core functionality can work offline and data can be stored and controlled by the user.
Key Features
- Aggregates and syncs records from many patient portals and major EMR vendors, including Epic, Cerner, Veradigm, OnPatient/DrChrono, and VA sandbox integrations
- Timeline view and quick summaries to browse clinical encounters, medications, labs, and documents
- Local-first, offline-capable architecture with optional server-side components for syncing and multi-device use
- OAuth2-based integrations requiring provider client credentials for secure API access
- Docker-ready deployment and local development using an Nx monorepo and TypeScript stack
- Privacy-first defaults and user control over data storage and sharing
Use Cases
- Consolidate a patient's scattered medical records into a single, searchable timeline for personal use or clinical review
- Maintain a portable, local-first PHR for visits, second opinions, or transitions of care
- Automate periodic syncing from multiple hospital portals to keep records up to date without relying on third-party services
Limitations and Considerations
- Connecting to many EMR providers requires registering OAuth client credentials with each vendor and configuring environment variables; setup can be technical
- VA production access and some provider integrations may be limited or require sandbox credentials; feature availability depends on provider APIs
- Not a turnkey HIPAA compliance solution out of the box; deployment, hosting, and operational controls determine regulatory compliance
Mere Medical is aimed at users who want a privacy-conscious, self-hosted PHR with offline capabilities and broad portal coverage. It is actively developed and geared toward technically comfortable users or administrators who can manage OAuth client setup and containerized deployments.
