Show HN: Petal, open-source CoScreen/ScreenHero finally free

Petal is an open-source alternative to CoScreen and ScreenHero that enables collaborative screen sharing with real-time remote control capabilities. The platform allows multiple users to simultaneously share interactive windows that appear as movable, resizable elements on the desktop, with support for labeled user cursors and instant keyboard/mouse input. Users can choose between using Petal Cloud, self-hosting with LiveKit infrastructure, or fully customizing the open-source version for their specific needs.
