Open WebUI

Open WebUI, formerly Ollama WebUI, is a self-hosted web interface for large language models that runs entirely offline. It connects to Ollama and any OpenAI-compatible API and includes a built-in inference engine, retrieval-augmented generation over uploaded documents, chat history, model switching, and multi-user accounts with role-based access. Distributed via Docker or pip and released under a permissive open-source license.
