Open WebUI
Free self-hosted AI chat interface for Ollama and OpenAI-compatible APIs.
AI Chat
What you get
A self-hosted ChatGPT-style interface for local models through Ollama or any OpenAI-compatible API, with RAG, tools and multi-user support, able to run fully offline.
How to get it
Install with Docker or pip from docs.openwebui.com.
What it requires
Your own server, plus local models or an AI provider API key.
The catch
Not standard open source: the Open WebUI License requires keeping the Open WebUI branding in deployments with more than 50 users. You pay for any hosted models you connect.
