Open WebUI

What is Open WebUI?

Open WebUI is a self-hosted platform that gives you one chat interface for local and cloud language models. You can talk to Ollama, OpenAI, Anthropic or any OpenAI-compatible provider, run two models side by side, attach files and images, search the web, execute Python, and use voice, image generation and scheduled automations. Its knowledge features cover RAG with 13 vector databases, hybrid BM25 and vector search with reranking, several document extraction engines and a full-context mode. You can wrap a base model with instructions, tools and knowledge to build specialized agents, extend it with Python tools, MCP or OpenAPI servers, and give agents a real computer through Open Terminal. Notes and Channels support shared work with @model tagging. Administrators get access control and can connect LDAP, Active Directory or SSO, and the app can run on-premise or air-gapped. Standard use with the original branding is free; white-labeling or enterprise-only features need an enterprise license, quoted by the sales team.

Use cases

• Chat with local and cloud models in one interface
• Build a private knowledge base with RAG
• Create specialized assistants from base models
• Deploy a self-hosted AI platform for a team
• Compare two models side by side
• Run code and agent tasks with Open Terminal
• Schedule recurring prompts as automations

Who it's for

• IT and platform teams
• Developers
• Enterprises needing self-hosting
• Privacy-conscious users

Why use Open WebUI

• Keeps data on your own infrastructure, including air-gapped deployments, instead of sending it to a hosted chat service.
• Avoids vendor lock-in by letting you mix local models with commercial APIs in the same workspace.
• Replaces separate tools for chat, document search, notes and image generation with one interface.
• Lets administrators control which users and groups can reach which models and tools.
• Scales from a single Docker container to multi-replica deployments behind a load balancer.
