The short answer
Self-hosting a ChatGPT alternative means running a chat frontend + a model on your own hardware. AnythingLLM (64,364 stars, MIT) is the easiest all-in-one with document workspaces; Open WebUI (147,900 stars) is the most feature-rich (RAG, web search, multi-user); chat-ui (10,866 stars, Apache-2.0) is Hugging Face's minimal codebase that powers HuggingChat.
