An immutable clinical OS built for reality
Legacy veterinary software overwrites history and breaks under real-world chaos. VetOS is event-sourced, offline-first, and fail-closed—so every record is defensible and every workflow survives outages.
The switch triggers legacy systems can’t handle
VetOS is engineered around immutable truth, offline reality, and fail-closed invariants. This is what makes clinics comfortable leaving decades of legacy.

Want to switch
Different category. Different outcome.
VetOS isn’t “better software.” It’s an immutable clinical operating system built for reality, not demos.
Speed of AVImark
Core actions in 3-5 clicks. Keyboard-first design matches the muscle memory you've built over decades. No learning curve.
Integrity of Cornerstone
Penny-perfect financials. EOD reconciliation that cannot drift. Replay from genesis always equals current state.
Freedom of an open ledger
Your data is yours. Export anytime in open formats. No vendor lock-in. No hostage situations.
What you get that legacy can’t provide
The competitive matrix is explicit: VetOS is event-sourced, offline-first, and designed for deterministic rebuilds and forensic auditability.
Your current system wasn't built for today
Legacy PMS systems were designed before smartphones existed. They assume always-on internet, centralized servers, and vendor control of your data.
Audits shouldn't be scary
When regulators or insurers ask questions, you should have answers in seconds—not days of digging through paper trails and fragmented records.
Offline isn't optional
Rural practices, mobile units, and emergency situations need software that works without internet. Period.
Your data belongs to you
You built your practice. You should be able to leave any vendor anytime, with all your data, in formats you can actually use.
