What is Open WebUI?

Open WebUI is a self-hosted platform for using AI models through a shared interface. It connects to Ollama, OpenAI, Anthropic, and compatible providers, letting individuals and organizations work with local models, cloud services, or a combination of both. Conversations, model configurations, and tools are brought together in one place.

Users can install Open WebUI with pip or Docker and run it on their own infrastructure without creating an account. Its toolkit includes voice interaction, vision, retrieval-augmented generation, search, and code execution. Python extensions and pipelines let users add capabilities, while a community library provides reusable prompts, model configurations, tools, functions, and skills.

For organizational deployments, Open WebUI offers single sign-on, role-based access control, audit logs, and data residency options. It supports on-premises and air-gapped environments for teams with stricter infrastructure requirements. The platform provides the interface and integration layer; users connect the models they want to use and choose where those models run.
