The short version

  • Only GNU Health has a free tier, so it costs nothing to try first.
  • Each has a real cost: Ambra Health intelerad now owns Ambra and ambrahealth.com redirects to Intelerad client support, so a buyer is committing to the Intelerad portfolio roadmap and should get written positioning on Ambra versus Intelerad own cloud PACS before signing.; GNU Health development depends on GNU Solidario, a very small nonprofit funded by donations and training, so release cadence and long-term continuity are tied to a handful of people rather than to an engineering organisation.
  • They diverge on capability: Ambra Health covers Image exchange, GNU Health covers Electronic medical record.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Ambra Health

  • Intelerad now owns Ambra and ambrahealth.com redirects to Intelerad client support, so a buyer is committing to the Intelerad portfolio roadmap and should get written positioning on Ambra versus Intelerad own cloud PACS before signing.
  • Ambra is built for cross organisation exchange, not for high volume in department diagnostic reading, so a radiology group that expects it to replace a departmental PACS finds the reading ergonomics and hanging protocols thinner than a dedicated PACS client.
  • Pricing scales with study volume and stored capacity, so a health system that turns on patient upload broadly sees storage grow from low value outside studies it never intended to retain, and the renewal reflects that.
  • Identity reconciliation of studies arriving with foreign patient identifiers still needs human review at volume, and sites that budget for zero touch matching end up staffing an imaging records queue.
  • Adoption depends on referring practices actually using the portal, and the vendor cannot make that happen, so image exchange projects frequently stall at the outreach and change management step rather than at the technology.

GNU Health

  • Development depends on GNU Solidario, a very small nonprofit funded by donations and training, so release cadence and long-term continuity are tied to a handful of people rather than to an engineering organisation.
  • It is built on Tryton, a framework few health IT staff know, so hiring or contracting people who can extend and maintain it is materially harder than for a mainstream stack.
  • Installation, upgrades and database administration assume Linux and Python competence, which puts the real cost on staffing rather than on licensing and defeats hospitals that lack that team.
  • The interface is functional rather than designed, and clinician acceptance is a genuine deployment risk compared with commercial systems that have invested heavily in usability.
  • Certification, regulatory conformance and interoperability testing that some jurisdictions demand of clinical systems are not provided by a vendor, so the adopting institution has to carry that work and that liability itself.

Answered from the vendors’ own pages

Ambra Health: Is Ambra Health still sold under its own name?

Yes. Intelerad still markets Ambra Health as a named product line, but the standalone website redirects to Intelerad, and support and contracting run through Intelerad.

GNU Health: Who develops GNU Health?

GNU Solidario, a Spanish nonprofit NGO, as an official GNU package under the GPL.

Ambra Health: Can Ambra replace our PACS?

For image exchange, archiving and clinical viewing, yes. For high volume diagnostic radiology reading it is generally deployed alongside a departmental PACS rather than instead of one.

GNU Health: Is there commercial support?

Yes, in a limited form, from GNU Solidario itself and a small number of implementers. It is not a vendor support organisation.

Ambra Health: Is pricing published?

No. It is quoted by annual study volume, stored capacity and the scope of exchange connections.

GNU Health: What is it built on?

Tryton, a Python business application framework, which is where its accounting, stock and HR modules come from.

Ambra Health: Does the viewer require software on referring physician machines?

No. The viewer is zero footprint HTML5, which is the main reason referring practices adopt it at all.

GNU Health: Is it suitable for a large hospital?

It is deployed in hospitals, but the deciding factor is whether you have internal Linux, Python and Tryton capability rather than the size of the institution.
