About Open WebUI

Open WebUI is an open-source, self-hosted AI platform designed to give users complete control over their AI infrastructure. It serves as a comprehensive interface for running AI models on personal hardware, in the cloud, or both, with support for connecting to various model providers such as Ollama, OpenAI, and Anthropic. The platform emphasizes data sovereignty, allowing users to keep their data and models on their own machines, and is built to scale from individual use to enterprise deployments with features like SSO, RBAC, audit logs, and air-gapped deployment options. Open WebUI also includes a community-driven ecosystem where users can share and discover prompts, models, tools, functions, and discussions, fostering a collaborative environment for AI development and usage.
