cindy

Cindy is an open source AI agent that runs on your own machine and actually does the work, driving Claude Code or Codex, controlling a browser or the computer, and reaching into third-party apps. It ships as a desktop and mobile app with native binaries bundled in, so it's closer to a finished product than a framework you assemble.

The client is Apache 2.0 and works fully local, including a "Skip Sign-In" path, so you can run it without an account and keep everything on your device. That's the free core, and for a lot of people it's the whole thing.

Solo users and small teams can run it free against their own model keys. The monetization is an optional official Cindy service that bills model usage transparently, which is the sensible route for teams that want a managed backend instead of wiring up their own.

The catch is maturity. Cindy is early and it shows, a large open-issue count and the rough edges you'd expect from a fast-moving agent app. The direction is good and the local-first stance is the right one, but test it on real tasks before you trust it with anything that matters.
