# Best open source AI tools for hospitals and healthcare

> For hospitals and healthcare teams, the core of a private AI stack is Ollama for running open models locally, LibreChat for a private chat interface and RAGFlow for answering questions over your documents, all running on your own servers so patient data can stay on your infrastructure. Each pick was chosen by hand for its job and is shown with GitHub data from October 2026.

Patient data is the main reason hospitals hesitate to use cloud AI. A self-hosted stack runs open models on your own servers, so clinical notes and documents never leave your infrastructure.

## How this list was made

- Apps were picked by hand from the appsgit catalog for each job, then checked against the snapshot: unknown or archived projects and projects with no commit in two years are dropped automatically.
- Inside each section the curated order is kept, most broadly useful first; an app appears only once on the page.
- Stars, license, Docker and activity facts come from the GitHub API as of October 2026.
- Source-available apps are labelled; they are not open source, so read their licenses before commercial use.

## FAQ

### Is self-hosted AI safe for patient data?

Running the model, chat interface and document search on your own servers means patient data is not sent to an outside AI provider. You still need HIPAA, GDPR or local processes: access control, encryption, audit logs, a risk assessment and clinical review of AI output. This page is not legal advice.

### Can these tools transcribe clinical dictation?

Whisper ASR Webservice is a speech recognition service built on OpenAI Whisper that you run yourself. Accuracy on medical vocabulary varies by model and audio quality, so test it on your own recordings before relying on it.

### What hardware do I need to run AI models myself?

Small open models run on a modern CPU with 16 GB of RAM, but a GPU with enough video memory for the model you pick makes answers much faster. Start with a small model in Ollama, measure the speed on your own hardware, then size up.

### Is Ollama free?

Yes. Ollama is open-source software released under the MIT 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?

All 19 apps here publish Docker images, including Ollama, LocalAI and LLM Harbor, 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.
