Best open source software for hospitals and healthcare

For hospitals and healthcare providers, a self-hosted stack starts with OpenEMR for patient records, Cal.diy for appointments and Paperless-ngx for consent forms and documents. Each pick was chosen by hand for its job and is shown with GitHub data from October 2026.

Healthcare teams self-host to keep patient data on infrastructure they control. The catalog has two clinical systems, OpenEMR for records and practice management and OpenELIS Global for laboratories; the rest of this stack covers scheduling, documents, communication and identity.

FAQ

Questions and answers

Still curious? Email info@appsgit.com.

What is the best open source software for hospitals and healthcare?

For hospitals and healthcare providers, a self-hosted stack starts with OpenEMR for patient records, Cal.diy for appointments and Paperless-ngx for consent forms and documents. Each pick was chosen by hand for its job and is shown with GitHub data from October 2026.

Is OpenEMR HIPAA compliant?

Software alone is never HIPAA compliant; compliance depends on how it is hosted, secured and operated. OpenEMR gives you a self-hosted electronic health record, and you remain responsible for encryption, access control, audit logging, backups and business associate agreements.

Can a small clinic self-host this stack?

Yes, most of these apps run on a single server, and all but a few ship Docker images. A clinic without IT staff should still budget for someone to handle updates, backups and security, or use a managed host that signs the agreements your rules require.

Is OpenEMR free?

Yes. OpenEMR is open-source software released under the GPL-3.0 license, so you can self-host it at no cost. You only pay for the server it runs on, and some projects also offer an optional paid cloud plan.

Can I run this stack with Docker?

14 of the 17 apps here publish Docker images, including OpenEMR, OpenELIS Global and Cal.diy, so most of the stack can run side by side with Docker Compose on one server. Size the server for the heaviest app and add off-site backups.
