Fasten Health

aid: fasten-health
name: Fasten Health
description: Fasten Health is a healthcare data interoperability company offering a unified medical record platform that gives
  patients and developers access to clinical data across the U.S. healthcare system. Fasten began as an open-source project
  — Fasten OnPrem, a self-hosted personal/family electronic medical record manager that ingests FHIR Bundles and is distributed
  under GPL-3.0 with 2.7k+ GitHub stars. The team then productized the connectivity layer as Fasten Connect, a commercial
  REST + FHIR API and Stitch client SDK suite that lets developers retrieve clinical records from 50,000+ healthcare systems
  and 60,000+ organizations including Epic, Cerner, MyChart, Kaiser Permanente, HCA, Ascension, Humana, and Medicare. Founded
  by engineers who lived through the fragmentation of health data firsthand and based in New York City, Fasten ships GPL/MIT/Apache
  2.0 open source repos alongside the hosted Fasten Connect platform.

  name: Fasten OnPrem
  description: Fasten OnPrem is an open-source, self-hosted, personal and family electronic medical record manager written
    in Go (47%) and TypeScript (35%). It runs as a Docker container behind HTTPS/TLS, supports multi-user family accounts
    with admin and viewer roles, and ingests medical data either through manual entry or by importing FHIR Bundles. It ships
    condition-specific dashboards and diagnostic test tracking, with planned vaccination-recommendation, conversational medical-history,
    and wearable-integration features. Distributed under GPL-3.0 with 2.7k+ stars; the official container image is hosted
    at ghcr.io/fastenhealth/fasten-onprem. STATUS - the repository was ARCHIVED (read-only) on GitHub as verified on 2026-08-14;
    last push 2026-02-13 and last tagged release v1.1.3 on 2024-10-01. The self-hosted product line is no longer under active
    development; Fasten's active work is the commercial Fasten Connect platform.

  description: Stitch is Fasten Connect's client-side embeddable component that lets a patient pick their healthcare provider,

    Web Component, a React SDK, and a React Native SDK — each with quickstart and reference docs. Client events stream connection
    lifecycle, error, and consent signals back to the host app. The Stitch element source repos (fasten-stitch-element-react,
    fasten-stitch-element-react-native) are MIT-licensed on GitHub with companion playground apps.
