Open WebUI
A self-hosted AI & Machine Learning app you can run on your own server.
Open WebUI is a self-hosted AI and machine-learning tool that you run on your own server instead of renting it as a cloud service. It is a practical pick for homelab users and teams who prefer owning their tools over renting them.
The project is developed in the open via GitHub, where it has earned 151.7K stars from the community. Repository activity was last recorded on Sep 4, 2026, and the project is classed as actively maintained in our snapshot.
Before you switch
Self-hosted AI tools reward a quick hardware check: chat interfaces are light, but local model runners need RAM and, ideally, a GPU. Start with a small model, confirm the interface connects to it, and only then scale up. Running AI on your own server keeps prompts and documents on hardware you control.
Like every project listed on SelfHosted, Open WebUI is developed in the open — you can read the code, follow development, and even contribute. Check the system requirements and the project’s own documentation linked on this page before installing.
