Beam.win

Beam.win: Beam is a macOS app that streams individual windows from one Mac to another over a network.

Beam puts a window from one Mac onto another with native feel, Retina sharp resolution, and real input. Instead of a video feed of a whole desktop, it hands you the window itself with its own Dock icon and a place in ⌘Tab. Windows go straight from Mac to Mac, encrypted over your own network or via Tailscale. It supports dragging files, copying and pasting, and sound traveling with the app. You can also view windows in a browser tab using share links. It runs on two Macs with Apple silicon on macOS Sonoma or later.
