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.; Open Dental uS support is $199 per month per location on an initial 12 month contract, dropping to $149 per month only after that year
  • They diverge on capability: GNU Health covers Electronic medical record, Open Dental covers Patient scheduling.
  • 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.

Open Dental

  • US support is $199 per month per location on an initial 12 month contract, dropping to $149 per month only after that year
  • The monthly fee covers up to 3 providers per location; each additional provider is $20 per month
  • Fees are charged per location, so a multi site practice pays for every office
  • eServices are charged separately per location, including eClipboard at $45 a month, ODMobile at $35 a month and eConfirmations at $25 a month
  • Electronic prescribing through DoseSpot costs $57 per month per prescribing provider
  • Conversion and implementation fees are not published and require consultation
