About

Petal provides multi-window screen sharing for pair programming. Shared windows appear as movable native windows, with simultaneous sharing and remote input. Requires macOS 13+; the universal build supports Apple Silicon and Intel. Screen Recording and microphone permissions are needed; Accessibility enables remote control. The publisher describes Petal as free and open source, with hosted or self-hosted LiveKit infrastructure. Remote control remains an early feature.
