Open WebUI
What is Open WebUI?
Open WebUI is a self-hosted interface for chatting with AI models and managing AI workflows. It connects to local models through Ollama and to cloud models through supported APIs, so users can choose where inference happens. Individuals, developers, and organizations can use it to bring conversations, document search, tools, and custom agents into one interface. Features include retrieval-augmented generation for uploaded knowledge, integrations with external tools, and an API for automation. The core software is free, while some enterprise-only offerings and larger deployments with altered branding require an enterprise license.
How to use Open WebUI?
- Install Open WebUI using a supported method such as Docker or pip, then open your running instance.
- Connect a local Ollama server or a compatible cloud provider using its endpoint and API credentials.
- Choose a connected model, send a prompt, and add files or tools to build out your chat workflow.
Open WebUI's Core Features
Local and Cloud Model Connections: Connect Ollama models and compatible provider APIs in one interface.
Multi-Model Chats: Compare responses from multiple selected models using the same prompt.
Document Knowledge and RAG: Upload reference files and let models retrieve relevant content for answers.
Custom Models and Agents: Combine a base model with instructions, tools, and knowledge for repeatable tasks.
Web Search: Let supported chat workflows retrieve online information and present cited sources.
Tool and Plugin Integrations: Extend model workflows with tools, functions, MCP, and OpenAPI-compatible servers.
File and Image Uploads: Attach supported content to conversations for model analysis.
REST API: Connect chats, files, and knowledge workflows to scripts and external applications.
User and Group Access Controls: Configure roles, groups, and permissions for shared deployments.
