Overview

Open WebUI is an open-source, self-hosted AI platform that provides a user-friendly interface for deploying and interacting with large language models (LLMs). Designed to function entirely offline, it ensures data privacy and security by allowing users to run AI models locally without relying on external servers. The platform supports various LLM runners, including Ollama and OpenAI-compatible APIs, and features a built-in inference engine for retrieval-augmented generation (RAG).
