Fasten Health

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.

Fasten Health publishes 1 API on the APIs.io network: Fasten Connect API. Tagged areas include Healthcare, FHIR, Personal Health Record, Electronic Medical Record, and Health Data Interoperability.

The Fasten Health catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Fasten Health’s developer surface includes authentication, documentation, GitHub presence, engineering blog, changelog, signup flow, pricing, and 44 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Health regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/fasten-health: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you?

    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
