Cindy is an open-source AI agent that works out of the box. She brings multiple harnesses, models and tools into one agent that finishes real work in your projects and apps — ready from day one, yours to shape over time. Run her on the official service, authorize the Claude Code / Codex Coding Plan you already pay for (no duplicate bill), connect your own API keys, or use local models — the software itself is free. Open source means more than visible: it means changeable.
Cindy 是一个开源、开箱即用的 AI Agent。她把多套 Harness、模型和工具收进同一个持续成长的伙伴，在真实工程和软件里把任务做完——一开始就好用，任你打扮，任你培养。官方服务登录即用，也可以一键授权你已有的 Claude Code / Codex Coding Plan（不必重复付费）、接你自己的 API key 或本地模型——软件本身免费。开源，不只是看得见，更是改得动。
