Why we included this project
Chat UI is the SvelteKit application that powers HuggingChat, which makes it a realistic reference for teams building an LLM chat product. It ships as a full deployable app rather than a component library: a polished chat interface with tool and multimodal support, MongoDB-backed user sessions, and routing across models. Because it talks to any OpenAI-compatible backend, from a local llama.cpp server to OpenRouter or Hugging Face's own router, a team can stand up a branded public chat service on the model endpoints it already uses without hand-building the whole interface.
