Bananas Screen Sharing is a user-friendly tool that allows you to easily share your screen on Mac, Windows, and Linux through a peer-to-peer connection. No account or server infrastructure is required, except for the initial connection information exchange with stun, turn, and signaling servers. To get started, simply download the latest release from the GitHub releases page. (Surprising: No account or server infrastructure needed; Unique: Peer-to-peer connection)
