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.; Zanda Health the 2024 rename from Power Diary means most third party reviews, integration guides and community answers still sit under the old name, so buyers researching Zanda Health find a thin trail and may wrongly conclude it is a new and unproven product.
  • They diverge on capability: GNU Health covers Electronic medical record, Zanda Health covers Unlimited admin users.
  • 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.

  • A multi site podiatry business that needs room and equipment allocation alongside practitioner availabilitynot 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.

Zanda Health

  • The 2024 rename from Power Diary means most third party reviews, integration guides and community answers still sit under the old name, so buyers researching Zanda Health find a thin trail and may wrongly conclude it is a new and unproven product.
  • North American billing is not properly served: there is no claims clearinghouse and superbill handling is basic, so a United States practice will need a separate revenue cycle tool and will pay for two systems.
  • Pricing is quoted in United States dollars while the company, support hours and product depth are Australian, so buyers outside those two time zones get support with an overnight lag on urgent clinical scheduling problems.
  • SMS is billed per message beyond the plan allowance and a dedicated number is required in the United States and Canada, so a busy clinic sending reminders and follow ups accumulates a variable monthly cost that is not visible in the headline plan price.
  • Reporting is adequate for a single clinic but weak for a group: cross site financial consolidation and practitioner productivity comparison generally end up exported to a spreadsheet, which becomes a monthly manual job as soon as you pass a handful of locations.

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.

Zanda Health: Is Zanda Health the same as Power Diary?

Yes. Power Diary rebranded to Zanda Health in 2024. Same company, same product line, same data.

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.

Zanda Health: Do receptionists count as paid users?

No. On the Growth plan administrative users are unlimited and free. Only practitioners are charged.

GNU Health: What is it built on?

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

Zanda Health: Does it handle Medicare bulk billing?

Yes, Medicare Online, DVA and bulk billing claims are submitted from within the platform for Australian practices.

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.

Zanda Health: Is it suitable for a United States practice?

Only partly. Charting, scheduling and telehealth work, but there is no claims clearinghouse, so US insurance billing needs a separate system.
