A small world starts with a good first step.

These docs describe the implementation on the development branch. The native Mac download is Developer ID signed and notarized by Apple, and checks for updates automatically from version 0.3.0.

Everything stays local. No account, cloud relay, or model-provider key is required by Quantum, and your projects never leave your machine. This website uses cookie-free Vercel Web Analytics and Speed Insights for anonymous page-view and performance counts; nothing you build is collected. Your chosen agent host may have its own requirements.
