Open WebUI is a highly feature-rich, self-hosted frontend interface originally built for Ollama, but now supporting all OpenAI-compatible APIs. It provides a polished, ChatGPT-like experience with massive extensions tailored for privacy-first AI deployments. In 2026, it is the premier choice for organizations replacing commercial SaaS AI subscriptions with self-hosted alternatives. Open WebUI goes far beyond simple chat; it includes built-in multi-modal capabilities (vision, audio generation), document uploading for seamless local RAG, web search integration, and multi-model concurrent querying. It features a robust role-based access control (RBAC) system, making it perfect for deploying across a company where different departments need access to different models or knowledge bases. With its offline-first architecture, beautiful responsive design, and MIT license, Open WebUI brings enterprise-grade AI interactions entirely under your control.
docker run -d -p 3000:8080 -e OLLAMA_BASE_URL=http://host.docker.internal:11434 -v open-webui:/app/backend/data ghcr.io/open-webui/open-webui:mainYes, while optimized for Ollama, Open WebUI natively supports any OpenAI-compatible API, allowing you to use Claude, ChatGPT, or Groq alongside your local models.
Open WebUI uses local embedding models to process and store your documents within its own local vector database. None of the document data is sent externally unless you are specifically using a cloud LLM.
