GoKawiilPetal launches as free, open-source alternative to CoScreen and ScreenHero
Petal is a new screen-sharing tool, released as open source and free to use, that lets multiple users share windows simultaneously. Shared windows appear as movable, resizable desktop windows rather than static tiles, and participants can click, type and scroll inside them using labeled cursors with instant remote input.
GoKawiil's interpretation of the reporting above, not reported fact.
The project positions itself as a successor to CoScreen and ScreenHero, two collaborative screen-sharing tools that shut down or were discontinued, suggesting demand remains for real-time multi-user remote control rather than passive screen viewing. Being open source could let developers self-host or modify it, though its early-stage, community-driven nature may affect long-term support and polish.
- Petal offers interactive, multi-user screen sharing with real windows instead of grid tiles.
- It is free and open-source, unlike its predecessors CoScreen and ScreenHero.
- Supports simultaneous sharing and remote control via labeled user cursors.
