DeepSeek open-sources chat-demo, a backend-free browser chat UI for its API
huangyun_122 · x · 2026-11-15
DeepSeek released chat-demo on GitHub (MIT, 1.9k stars): a static chat app powered by the DeepSeek API with no backend — the browser connects directly to the API, and the release archive runs locally by double-clicking index.html after entering your API key.
Features: native deepseekwebsearch with multi-step reasoning, web retrieval and source citations in deep-thinking mode; parsing of PDF/Word/PPT/images plus automatic URL extraction; mobile real-time voice input and read-aloud; all data stored locally in IndexedDB. Dev setup needs Node.js 22.12+ and pnpm; pnpm dev serves it at localhost:8090.
