Score: 7.5/10 (Innovation: 7, Technical: 8, Documentation: 8, Utility: 7)

Petal is a low-latency, open-source multi-window screensharing tool that renders shared windows as native, movable desktop windows rather than meeting-grid tiles. Built with Rust and Tauri, it targets small engineering syncs and includes telepointers, drawing, remote control, and opt-in AI chat, with macOS as the mature client and Windows still in early development.

Target audience: backend devs, frontend devs, devops, and engineering teams doing remote pair programming
