Open WebUI is an open-source, self-hostable web interface for interacting with Ollama models and OpenAI-compatible APIs. It provides a ChatGPT-like interface that supports RAG document uploads, multi-user authentication, conversation history, model switching, and a plugin system for extending functionality. Self-hosting enthusiasts, small teams, and organizations wanting a private AI deployment use Open WebUI to run a full-featured AI chat interface on their own server, accessible to multiple users without each person needing technical setup. It proxies to Ollama running locally or on a shared server. Open WebUI has become the most popular frontend for self-hosted AI, with over 45,000 GitHub stars. Its rapid feature development, active community, and flexible deployment options (Docker, bare metal, cloud) have made it the default choice for anyone building a private AI deployment.
