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.; TheraNest the Essentials plan includes no insurance claims at all, so any practice that bills a payer is effectively on the 59 USD tier or above and the advertised 29 USD entry price does not apply to it.
  • They diverge on capability: GNU Health covers Electronic medical record, TheraNest covers Progress notes and treatment plans.
  • 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 practice moving off paper or a general purpose calendar that needs a client portal for intake forms and consent signaturesnot GNU Health
  • A behavioural health organisation that bills a steady volume of insurance claims each month and can size the Advanced allowance against its actual claim countnot 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.

TheraNest

  • The Essentials plan includes no insurance claims at all, so any practice that bills a payer is effectively on the 59 USD tier or above and the advertised 29 USD entry price does not apply to it.
  • Telehealth is only in the Premier plan, so a practice that wants video sessions pays 89 USD per therapist per month even if it needs nothing else from that tier.
  • An annual AMA CPT licence fee is billed separately each December on top of subscription cost, which surprises practices that budgeted only the monthly figure.
  • Additional administrative users are chargeable, so a practice with front desk and billing staff who never see clients still pays 19 to 29 USD per head for people who generate no revenue.
  • The product sits inside a consolidated portfolio that has already renamed the parent company from Therapy Brands to Ensora Health, and product investment in a portfolio is directed by the owner rather than by this product line, so roadmap commitments are worth less than they would be from a single product vendor.

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.

TheraNest: Is TheraNest still sold under that name?

Yes. The company rebranded from Therapy Brands to Ensora Health and the product is now marketed as TheraNest by Ensora Health, but you still buy TheraNest.

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.

TheraNest: Can I bill insurance on the cheapest plan?

No. Essentials includes no claims. Advanced includes 30 claims a month and Premier is unlimited.

GNU Health: What is it built on?

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

TheraNest: Are there hidden costs?

Two. Additional admin users are charged per head, and an AMA CPT licence fee is billed annually in December per therapist.

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.

TheraNest: Does it support group practices?

Yes, with per clinician reporting and payroll figures, though every clinician and every admin is a paid seat.
