  • 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.; Kareo kareo is now part of Tebra and sold under the Tebra brand rather than as a standalone product
  • They diverge on capability: GNU Health covers Electronic medical record, Kareo covers Electronic Health Records.
  • 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.

Kareo

  • Kareo is now part of Tebra and sold under the Tebra brand rather than as a standalone product
  • Tebra publishes no rate: pricing varies with provider count, features and implementation requirements and is quoted during a demo
  • Billing counts clinical providers such as MDs, DOs, NPs and PAs, so adding a prescriber raises the bill even though non clinical staff are free
  • Electronic prescribing of controlled substances setup costs about $75 per provider as a one time fee
  • PDMP integration costs $500 one time per facility plus about $50 per user per year

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.

Kareo: Are there discounts for adding multiple modules?

Yes. Tebra states that many practices qualify for bundled pricing or volume incentives when adopting multiple modules like EHR, billing, and patient experience tools together.

Source
GNU Health: What is it built on?

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

Kareo: What are the additional costs for controlled substance prescribing?

For providers who prescribe controlled substances, EPCS setup costs approximately $75 per provider as a one-time fee, and PDMP integration costs $500 one-time per facility plus around $50 per user per year.

Source
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.

Kareo: Does Kareo offer a free trial?

Kareo's website does not mention a free trial option. Access to pricing and trial arrangements requires contacting the sales team to request a demo.
