Open WebUI

Self-hosted web interface for local large language models.

Open WebUI provides a ChatGPT-style web interface that talks to Ollama, llama.cpp, vLLM, or any OpenAI-compatible endpoint. It adds conversation history, retrieval-augmented generation against local documents, model management, and multi-user authentication.

It runs on Linux as a Docker container or Python package and is the most widely used front-end for self-hosted LLMs.

docker run -d -p 3000:8080 ghcr.io/open-webui/open-webui:main
