What Open WebUI is

Open WebUI is a self-hosted interface for using local and cloud AI models, built to run entirely offline. It connects to Ollama and OpenAI-compatible APIs, and setup options include Docker, pip, uv, and desktop installation. Its listed capabilities span voice, vision, retrieval, generation, search, and Python extensions, as well as file uploads, image generation, mobile apps, integrations, and team workspaces. Extensions include Filters, Actions, Pipes, Tools, and Skills, with connections to MCP, MCPO, and OpenAPI tool servers. For knowledge retrieval, the project describes local RAG with nine vector databases, several content-extraction engines, hybrid search, reranking, and full-context mode. Organizations can deploy it on-premises, in a private cloud, or in an air-gapped environment. The operator chooses where chats, files, knowledge bases, and related data are stored; configuring external providers, tools, model endpoints, or integrations can route data externally. Security options include directory authentication, SSO, role and model permissions, and workspace isolation. The free plan costs nothing, with original branding intact; deployments over 50 users must retain branding unless an exception applies.

Who it suits
