Open WebUI is an extensible, feature-rich, self-hosted AI platform designed to operate entirely offline. It supports various LLM runners like Ollama and OpenAI-compatible APIs, with built-in inference engine for RAG. The project ships official Docker images that make deployment straightforward. It is frequently used as a front-end for local model runners or team AI gateways.
