Open WebUI Self-Hosted AI Interface for LLMs
Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform designed to operate entirely offline. It supports various LLM runners like Ollama and OpenAI-compatible APIs with built-in RAG inference, providing a powerful web-based interface for interacting with large language models.

Open WebUI is a comprehensive self-hosted AI platform that provides a polished web interface for interacting with large language models. Created by Timothy J. Baek, the project has grown into one of the most popular open-source LLM frontends with over 290 million Docker pulls and a thriving community of contributors.
Core Capabilities
The platform supports multiple LLM backends including Ollama for local models and any OpenAI-compatible API endpoint. This means you can connect it to LMStudio, GroqCloud, Mistral, OpenRouter, and other providers through a single unified interface. The built-in RAG (Retrieval-Augmented Generation) engine lets you chat with your own documents without external dependencies.
Key Features
Open WebUI ships with a native Python function calling system that lets you extend LLM capabilities through a built-in code editor. The Model Builder allows creating custom Ollama models directly from the web UI, and the community integration at openwebui.com provides a marketplace for sharing model configurations and tools.
Voice and video calling features support multiple Speech-to-Text providers (Local Whisper, OpenAI, Deepgram, Azure) and Text-to-Speech engines (Azure, ElevenLabs, OpenAI). The responsive design works across desktop and mobile, with full PWA support for offline access.
Agent Integration Points
For AI agent workflows, Open WebUI serves as a self-hosted frontend that agents can configure and manage. Its REST API allows programmatic model management, conversation handling, and RAG document indexing. The tool and function system enables agents to extend the platform with custom capabilities. Installation is straightforward via Docker: docker run -d -p 3000:8080 ghcr.io/open-webui/open-webui:main.
Deployment
The platform supports Docker, Kubernetes (kubectl, kustomize, or Helm), and pip installation. It includes granular role-based access control for multi-user environments and supports LDAP/OAuth authentication for enterprise deployments.
