Open Health Sync
Aggregate, standardize, and query health and wearable data through a unified API and Model Context Protocol interface.
Open Health Sync is an open-source, self-hosted health data aggregator that provides a privacy-first alternative to services like Terra. It consolidates disparate data streams from popular wearables and health platforms—including Apple Health, Health Connect, Oura, WHOOP, Garmin, and Dexcom—into a standardized format. Designed to deploy easily as a single Go binary paired with PostgreSQL, Open Health Sync exposes this unified data via REST, FHIR R4, Open mHealth, signed webhooks, export formats like CSV and Parquet, and a read-only MCP server, allowing AI agents to securely interact with personal health metrics without sending private data to third-party cloud services.
