Getting a "can't verify the developer" warning?
If you see a warning on first launch, go to System Settings > Privacy & Security and click "Open Anyway". Open source software usually isn't signed with an Apple developer certificate, which is normal.
Clicking "Download" takes you to a source confirmation page first; the download starts after confirmation.

Risk notice
The official release includes TapDB usage analytics, which collects only aggregate metadata such as device, OS, and version, and does not include conversation or file content. The macOS installer is not explicitly notarized, so Gatekeeper may block the first launch. Skipping sign-in will make server-related features unavailable.
Who it's for
- Developers who want to use an AI agent to accomplish real tasks in local projects.
- People who need to integrate Claude Code or Codex workflows and want to manage multiple models from one place.
- Users who value open source, auditability, and the ability to modify the client code themselves.
- Advanced users willing to use AI capabilities through the official hosted service or with their own API keys.
Who it's not for
- Users who need a Linux desktop version or mobile app packages (currently only macOS and Windows desktop versions are available).
- People who do not want to register an account but need full server-side features (such as cloud sync, automation).
- Users who want to fully self-host the backend and not rely on the official cloud service (the backend is not open source).

FAQ
Is Cindy free?
The client itself is free and the source code is open source under Apache-2.0. Using the official hosted service is billed based on usage (see pricing on the official website). You can also link an existing Claude Code / Codex coding plan, or use your own API key and local models.
Which operating systems are supported?
Currently, desktop packages are available for macOS (arm64 and x64) and Windows x64. There is no Linux version yet. Mobile versions (iOS/Android) are in development but no installer is available yet.
What is the difference between the -cn and -global versions?
The -cn version is for Cindy accounts in mainland China, while the -global version is for other regions. Choose according to the region you used when registering your account; otherwise you may not be able to log in or use the service properly.
How do I update to a new version?
The desktop app supports automatic updates, with update files fetched from the official CDN. You can also manually download the latest installer from the official website or GitHub Releases.
Can I use it without logging in?
Yes. You can select "Skip Sign-In" on the login screen to use the local agent, but server-related features (such as cloud sync, online automation, etc.) are unavailable, and the interface will show "Not signed in."
