OpenVPM vs ezyVet
ezyVet is a powerful cloud system with one of the better-documented APIs in the category. OpenVPM matches the openness and adds something ezyVet cannot: the source code.
ezyVet, owned by IDEXX, is a capable cloud-native PIMS popular with multi-site, specialty, and ER practices. Of the big closed systems it has one of the most openly documented APIs, which integrators appreciate. It is still proprietary, priced per user, and tied into the IDEXX ecosystem. OpenVPM offers a similar cloud experience and open API, plus the option to self-host for free and a public schema you fully control.
Pricing for other systems is publicly reported by third parties, not official rate cards. We aim to be fair. If something here is out of date, tell us and we will fix it.
What about your data?
ezyVet's API makes data more reachable than most closed systems, which is genuinely good. It is still a proprietary platform you do not control. OpenVPM gives you the same API access plus the code and schema, so the platform itself is yours.
