Open WebUI

Self-hosted web UI for running Ollama and OpenAI-compatible local LLM chat.

Overview

Open WebUI is a self-hosted AI platform designed for users who want to run AI on their own terms. It provides a unified interface to connect to any AI model—whether local via Ollama or cloud-based from providers like OpenAI and Anthropic—while keeping all data under your control.

The platform is built for scale, from individual laptops to enterprise deployments. It includes features like voice, vision, retrieval, generation, and Python-based function extensions. Users can install in under 60 seconds with a single pip command, and the community has grown to over 468,000 members sharing prompts, models, tools, and configurations.

Open WebUI emphasizes sovereignty and data residency, offering enterprise-grade controls including SSO, RBAC, audit logs, and on-premises deployment options for regulated industries.
