The short version

  • Only GNU Health has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Visage Imaging pricing is per exam against a minimum annual volume, so an organisation whose imaging activity is flat pays a floor while a growing one sees the software line rise every year rather than amortise.
  • They diverge on capability: GNU Health covers Electronic medical record, Visage Imaging covers Server-side rendering.
  • 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.

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.

Visage Imaging

  • Pricing is per exam against a minimum annual volume, so an organisation whose imaging activity is flat pays a floor while a growing one sees the software line rise every year rather than amortise.
  • Module breadth outside radiology is narrower than at Sectra or the large modality vendors, so a group planning to digitise pathology on the same platform will not find it here.
  • Server-side rendering shifts the cost to central infrastructure, so the saving on radiologist workstations is partly offset by what you spend on servers or cloud compute.
  • Pro Medicus concentrates on very large contracts, and smaller imaging groups report long sales cycles and little appetite from the vendor for deals below a certain volume.
  • Diagnostic AI is third party, surfaced through the accelerator framework rather than developed in house, so algorithm licensing, validation and monitoring remain the buyer problem.

Answered from the vendors’ own pages

GNU Health: Who develops GNU Health?

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

Visage Imaging: Who owns Visage Imaging?

Pro Medicus Limited, listed on the Australian Securities Exchange. That listing means major contract values and terms are publicly announced.

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.

Visage Imaging: How is Visage priced?

Per exam, against a minimum annual volume, on multi-year terms. Because Pro Medicus discloses large contract totals and durations to the market, buyers can estimate a per exam rate before entering negotiation.

GNU Health: What is it built on?

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

Visage Imaging: Is Visage 7 FDA cleared for diagnostic interpretation?

Yes, Visage 7 holds 510(k) clearance for diagnostic viewing including mammography and tomosynthesis on validated displays. Confirm the exact cleared modality list for your intended use.

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.

Visage Imaging: Does it work as a full cloud PACS?

Yes, Visage 7 runs complete PACS operations in the cloud rather than cloud viewing over an on-premise archive.
