Open Webui

Open WebUI is a self hosted AI platform that provides a single interface for working with language models while keeping data on the user's own hardware. It connects to local runtimes such as Ollama as well as cloud providers including OpenAI and Anthropic, or anything that speaks a compatible API, so one front end can serve many models. Beyond chat, the platform offers voice, vision, retrieval, image generation and web search. It is extensible with Python: users can build and install tools, functions that act as Python pipelines, custom models with their own persona and configuration, shared prompts, and reusable skills made of instructions and supporting files. A community hub on the website lets people browse and contribute these items. A recent release added realtime voice calls, animated 3D avatars, multi factor sign in, a Thinking slider for model controls, nested groups with per group default models, and version history for models, tools and skills. It runs locally or in the cloud and installs with a pip command or Docker, with no account required. For larger organizations the vendor describes single sign on, role based access control, audit logs, data residency, and on premises or air gapped deployment for regulated industries, offered through a sales conversation. The site does not publish prices. The software can be installed and run free of charge, and enterprise options are available by contacting the team.
