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

The founders of CoScreen, a screen sharing tool that was shut down by Datadog, have created an open-source alternative called Petal, which offers a similar experience with shared windows, multiple cursors, and real-time collaboration. Petal is completely free and open-source, with a hosted instance available or the option to self-host it. The tool runs on macOS, Windows, and a web app, with Linux support coming soon. The team is seeking community involvement to help develop and maintain the project.
