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.; Lunit the regulatory permission differs by product and by region, and INSIGHT Risk has been filed with the FDA but not cleared, so a buyer who reads a corporate press release rather than the specific clearance for their product and jurisdiction will plan a deployment they cannot legally run.
  • They diverge on capability: GNU Health covers Electronic medical record, Lunit covers Lunit INSIGHT MMG.
  • 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.

GNU Health

  • A breast centre that moved to tomosynthesis and now has reading times it cannot staff, wanting detection support on DBT specificallynot GNU Health
  • An American breast imaging centre needing automated volumetric density assessment to meet patient density notification requirements, which is what Volpara is bought fornot GNU Health
  • A tuberculosis or lung screening programme in a high volume, radiologist scarce setting using chest radiography triage to prioritise filmsnot GNU Health

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.

Lunit

  • The regulatory permission differs by product and by region, and INSIGHT Risk has been filed with the FDA but not cleared, so a buyer who reads a corporate press release rather than the specific clearance for their product and jurisdiction will plan a deployment they cannot legally run.
  • Detection AI changes recall rates in screening, and the downstream cost of additional diagnostic workup lands on the programme rather than on the software budget, which is the cost most screening business cases omit.
  • Performance is sensitive to the mammography vendor and acquisition protocol, so published results from a Hologic estate do not transfer to a GE or Siemens estate without local validation the buyer must fund.
  • MMG, DBT and CXR are licensed separately and Volpara modules are separate again, so a breast centre wanting detection, density and risk pathways is assembling four line items rather than buying one product.
  • Using AI as a replacement for one of two human readers is a workforce and liability decision that regulators and professional bodies treat differently in each country, so the saving that justifies the purchase may not be permitted where you operate.

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.

Lunit: Is Lunit FDA cleared?

Yes for specific products. INSIGHT MMG, INSIGHT DBT and INSIGHT CXR Triage hold FDA 510(k) clearances. INSIGHT Risk, the five year risk prediction model, has been filed but was not cleared at the time of writing.

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.

Lunit: Can Lunit replace a second human reader in screening?

That depends entirely on your jurisdiction and professional body guidance, not on the software. The CE mark permits clinical use; it does not authorise a workforce model.

GNU Health: What is it built on?

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

Lunit: What did the Volpara acquisition add?

Volumetric breast density measurement, dose tracking and RiskPathways high risk programme management, which are the things American breast centres buy for density notification compliance rather than for detection.

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.

Lunit: Is pricing published?

No. It is quoted per study or per annual volume, by product, with on premises and cloud priced differently.
