Open WebUI

★ 100k

The de-facto self-hosted ChatGPT interface: talks to Ollama and any OpenAI-compatible API, with RAG, tools, and multi-user.

Open WebUI does the job of ChatGPT Plus, self-hosted. It is BSD-3 (modified)-licensed, so you can do essentially what you like with it, and it installs in about one command. ChatGPT Plus bills $20/mo for it. 100k stars on GitHub.
