Overview
Open WebUI is a self-hosted, feature-rich chat interface that can run entirely offline while integrating seamlessly with Ollama runners and any OpenAI-compatible API. It offers a polished UI and ships with a built-in retrieval-augmented-generation (RAG) engine so you can keep both your data and your model on-premises.
Key Capabilities
- Multi-model support (Ollama, OpenAI, LM Studio, Groq, Mistral, etc.)
- Plugin / Function system for custom tools
- Integrated RAG pipeline for private knowledge-base Q&A
- Role-based access & multi-user workspaces
