The veterinary industry's open-source moment is here.
Live demo: no account · Trial: no card · Your data stays yours
Start with the gap, not a migration.
You do not need to buy an entire PIMS before one useful workflow can save your team time.
Pick one missing tool
Start with AI, client communication, reporting, or a clean copy of your data.
Bring only what it needs
Use sample data first, then import the clients and records for that workflow.
Expand when it earns it
Keep your current PIMS in place. Move more work only after OpenVPM proves useful.
The PIMS market is broken.
Everyone knows it.
Commercial systems charge $200 to $600+/month, lock you into proprietary data formats, and deliver software that frustrates your team daily.
Patient history lives in a proprietary format you can't fully export. Switching costs are enormous, so practices stay put even when the software frustrates them daily.
Most systems ship no real API, or charge thousands a year for read-only access. The tools and AI you'd want to build can't reach your own records.
Interfaces designed in the mid-2000s and bolted onto ever since. Click-heavy, slow, and the feature requests you file tend to go nowhere.
Meanwhile, AI is arriving and most PIMS have closed APIs that make it impossible for AI tools to read or write patient data. There is no widely adopted data interoperability standard in veterinary medicine.
Until now.
Everything your practice needs.
Nothing you don't.
A complete suite of tools designed for real veterinary workflows, from the moment a client calls to the moment they walk out the door.
Smart Scheduling
Day/week views with column-per-doctor layout. Drag-and-drop rescheduling, recurring appointments, automated reminders, and full status tracking from booking to checkout.
Complete Medical Records
SOAP notes, lab results with reference ranges, prescriptions with refill tracking, vaccination records with certificate generation, and AI scribe integration.
Billing & Invoicing
Charges auto-populate as services are administered. Estimates convert to invoices. Payment tracking, account balances, and end-of-day reconciliation.
Patient Management
Comprehensive profiles with weight trend charts, allergy alerts, photo uploads, microchip tracking. Multi-pet households linked to single clients.
Client Communication
Unified inbox across calls, texts, emails, and portal messages. Two-way SMS. Bulk campaigns. Every interaction logged on the client record.
Built for Compliance
DEA-compliant controlled substance logging, complete audit trails, role-based access control, and full data export at any time.
Inventory Management
Stock levels with reorder alerts, lot/batch tracking with expiration dates. Auto-deduction when dispensed from medical records. Purchase order generation.
Live Whiteboard
Real-time patient status board showing every patient in the building: doctor, room, status, procedure. Updates live across all screens via WebSocket.
Reports & Analytics
Revenue trends, appointment utilization, production by doctor, species distribution, client retention. Dashboard KPIs at a glance. Export to CSV/PDF.
A real, open API.
The first of its kind.
Every action the UI performs goes through the same API available to third-party integrations. 150+ endpoints with full documentation, webhook subscriptions, scoped API keys, and rate limiting.
No other open-source veterinary PIMS has a documented, read-write API. This is what makes OpenVPM the platform the industry can build on.

}Built for the AI era
OpenVPM's structured data and open API make it the ideal foundation for veterinary AI. The PIMS is the system of record. AI agents are first-class citizens.
Voice Agents
Book appointments, process refill requests, and complete intake forms over the phone
AI Scribes
Write SOAP notes directly into the medical record from conversation transcripts
Diagnostic AI
Read lab results, patient history, and write differential diagnosis suggestions
Proactive Outreach
Query overdue vaccinations and pending follow-ups to automate client communications
Don't switch. Connect.
You don't have to rip out the system you already run. Connect OpenVPM to your current PIMS and keep a live, open copy of your own data (patients, clients, visit history) in a system you control and can export any time. A second PIMS that you own.
Live mirror
Connect once. Your practice data flows into OpenVPM and stays in sync. Your records, in a system you hold the keys to.
Open by default
Everything sits behind a documented REST API with scoped keys. Read it, build on it, export it in full, with no proprietary formats and no lock-in.
Zero disruption
Your team keeps working in the tools they know. OpenVPM runs alongside, read-only until you decide to do more with it.
An agent that runs the busywork.
OpenVPM ships with an AI agent that works directly on your practice data through the same open API. Ask it to surface overdue vaccinations, draft recall outreach, pull a patient's history, calculate a weight-based dose, or book a visit. It uses real tools, not guesses, and every write is gated for your review.
Bring your own model key. Open source, inspectable, and scoped to your practice. The agent can only ever touch your own data.
Why open source matters for veterinary medicine
The veterinary industry is at a crossroads. AI is arriving. Data interoperability is becoming critical. And the dominant vendors are still charging hundreds per month for software that crashes, frustrates staff, and locks clinics into proprietary ecosystems.
Own Your Data
Export everything, any time. No lock-in, no proprietary formats. Your practice data belongs to you, period.
Zero Software Cost
Invest the $200–600/month you were paying for a commercial PIMS back into your team instead.
Community Roadmap
Features are built because practices need them, not because a sales team prioritized them for a quarterly target.
Innovation Platform
An open API means the next generation of veterinary AI tools can be built on a foundation that actually works.
What practice owners told us
“Show me software that actually reduces our staff hours. That's the only thing that matters.”
That's exactly what we're building. OpenVPM is designed from the ground up to make every team member faster, from the front desk to the exam room.
Use OpenVPM your way.
It's open source, so it's yours. Free to run yourself, forever. When you'd rather not run servers, we host it for you.
Self-host
It's open source, so it's yours. Run the full PIMS on your own infrastructure, with nothing held back.

- Every module and the complete API
- Docker or Vercel deployment paths
- Bring your own database, email, SMS, and AI keys
OpenVPM Cloud
Where we can be helpful: we host, update, monitor, and back it up so your team can just use it.
- Managed database, storage, backups, and updates
- Every module and role, unlimited staff
- 1,000 AI actions + 1,000 SMS included monthly
