Open WebUI
Self-hosted ChatGPT-like interface for local LLMs
Open WebUI (formerly Ollama WebUI) is a feature-rich, self-hosted web interface for running local LLMs. With 70K+ GitHub stars, it provides a ChatGPT-like experience for Ollama and OpenAI-compatible APIs. Beautiful UI, conversation history, RAG support, model management, and multi-user capabilities—all running on your own infrastructure.
Why Open WebUI?
Running LLMs locally with Ollama is powerful, but the command-line interface isn't ideal for everyone. Teams need a familiar chat interface, conversation history, and collaboration features. Without a proper UI, the barrier to adopting local AI remains high, especially for non-technical users who are accustomed to ChatGPT's polished experience.
How It Works
Open WebUI provides a complete web-based interface that connects to Ollama or any OpenAI-compatible API. It stores conversations locally, supports multiple users with role-based access, includes RAG capabilities for chatting with documents, and offers a model management interface. Deploy once, and your entire team can access local LLMs through their browser.
