AgentsOpen WebUI
A free, self-hosted, ChatGPT-style web interface you run on your own computer or server. It has no models of its own: it sits on top of Ollama or any OpenAI-compatible API and adds chat history, documents and multiple users.
✓ Last verified October 15, 2026 from official sourcesFree, self-hosted. You pay only for any cloud model API you choose to connect.
- A private ChatGPT-like experience on local models
- Sharing one local AI setup with a household or team
Self-hosted: chats and accounts stay in its own storage on your machine. A stock install makes a few outbound checks (version, model list) that can be switched off. Skill level: Intermediate.
What it's great at

- Multiple users on one machine
What it can do
- Officially recommended install is one Docker command; opens at http://localhost:3000
- Finds Ollama on the same machine automatically
- Chat with files, knowledge bases, web search, tool calling
- User accounts with an admin who approves sign-ups
Example tasks to try

Start in 5 minutes
