Thanks! The backend and chrome extension is not yet open source, but we have to do some work to make that possible expected in the next week. It performs best with Gemini Pro 1.5, so the backend is important for now, but long term we can switch to a local model as soon as possible.

The chrome extension is required to target off-screen elements, using a websocket server locally. This allows a 100% replacement for previous selector strategies.

If you are interested in contributing email me at rohan@cheatlayer.com and I can help get you set up.
