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.; OpenClinica the free community edition is a different and older product line from the commercial platform, so evaluating the open source build tells you little about what the paid product actually does.
  • They diverge on capability: GNU Health covers Electronic medical record, OpenClinica covers Open source community edition.
  • Prices and features above were last checked on 1 September 2026.

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.

OpenClinica

  • The free community edition is a different and older product line from the commercial platform, so evaluating the open source build tells you little about what the paid product actually does.
  • The vendor provides no support or services at all for the community edition, which means outages, patching, database upgrades and validation documentation are entirely your problem.
  • Commercial pricing is not published, so you cannot benchmark it against alternatives without entering a sales process, and third-party figures around USD 1,000 a month are indicative rather than contractual.
  • Study build is skilled work: complex edit checks, randomisation schemes and integrations usually mean paying for vendor or consultant configuration services on top of the licence, which is a frequently underestimated line in the budget.
  • As a smaller vendor than the large eClinical suites it has a thinner partner and consultant ecosystem, so finding experienced build staff or a CRO already fluent in the platform is harder than with the market incumbents.

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.

OpenClinica: Is OpenClinica free?

There is a genuinely free, LGPL licensed community edition you host yourself with no vendor support. The commercial platform with eConsent, eCOA and a validated hosted instance is quoted and paid.

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.

OpenClinica: Is the open source version still maintained?

Yes, releases on the 3.x line continued through 2025, but it is a separate and older architecture from the commercial product.

GNU Health: What is it built on?

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

OpenClinica: Does it meet 21 CFR Part 11?

The commercial hosted platform is built for Part 11 and GCP compliance. If you self-host the community edition, compliance and validation are entirely your responsibility.

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.

OpenClinica: What does the commercial version cost?

Not published. Third-party listings suggest enterprise arrangements from around USD 1,000 per month, but real cost depends on study count, subjects, modules and build services.
