Digital health companies and value-based care teams that need a patient's records from other providers often choose between Metriport and Particle Health. Both pull those records from national health information exchanges through one API, so a team's software can get a patient's outside history without a separate interface to each hospital. Metriport publishes its code as open source, and Particle Health has been selling network access for longer.
Digital health companies and startups that want outside records through one API
Health systems that want a long-established vendor with many years of references
Digital health and mid-market providers that need longitudinal records through a clinical data network
Teams without privacy, BAA, and data-governance bandwidth
| Axis | Metriport | Particle Health |
|---|---|---|
| Getting usable outside records | Metriport scores 7.2 for records access, delivering each patient's data as one record in FHIR, the standard format for exchanging health data. | Stronger Particle scores 7.6, with the best results when retrieved charts feed a live workflow such as intake or care management. |
| Network and API product | Data arrives through an API, a data warehouse, EHR apps, or an embedded dashboard. | Stronger Particle retrieves records across the network and condenses long histories into something a care team can use. |
| Open-source code | Stronger Engineers can read Metriport's open-source code before the company signs a contract. |
Particle's API is commercial software without public source code. |
| Getting the integration live | Stronger One integration gets a team connected, and it needs engineers who can work with an API. |
Production use needs a security review, checks on how well patients are matched, and ongoing data-quality work. |
| Knowing what you will pay | Usage-based quotes scale with patients queried, alert volume, and add-ons such as AI summaries. | Stronger Contracts are tied to how many records a team retrieves, plus services for the first use cases. |
| Track record | Metriport was founded in 2021 and in August 2026 listed Amazon One Medical, Sollis Health, and Color Health as customers. | Stronger Particle Health, founded in 2018, has the longer record of the two with customers. |
Particle Health is for a digital health company or provider group that wants outside records feeding a live workflow such as intake, risk scoring, or care management, and prefers the vendor with the longer track record. Metriport is for an engineering-led team that wants to read the code before signing, wants every record in FHIR, and can use AI record summaries and care-gap flags.
Walk away from both if no engineer can own the API, or if all you need is one interface between two EHRs.
