## What it is
Open WebUI is a self-hosted, extensible web interface for interacting with large language models, supporting Ollama, OpenAI-compatible APIs, and a built-in inference engine for RAG. It offers user management with RBAC, plugin/tool extensibility via MCP and OpenAPI tool servers, and can run fully offline.

## Use cases
- self-host a ChatGPT-like interface for local Ollama models
- chat with multiple LLM providers from one UI
- build RAG pipelines over my own documents
- create custom AI agents with tools and knowledge
- deploy an offline AI chat platform for a team with user roles
- connect MCP and OpenAPI tool servers to my LLM

## When to choose
- you want a polished, self-hosted web UI for Ollama or OpenAI-compatible backends
- you need multi-user access control, RBAC, and offline operation
- you want built-in RAG, agents, and plugin/MCP extensibility in one platform

## When to avoid
- you need only a lightweight headless API gateway without a chat UI
- you require a permissively licensed library to embed in your own product (license is custom, not standard open source)
- you want a minimal single-user desktop-only chat client
