Beam for Mac launches with a promise to bring app windows from another Mac

In his Product Hunt maker comment, Shah says you can choose an app window on another Mac and open it alongside the apps on the Mac you’re using. He says the window gets its own Dock icon and appears in ⌘Tab. He says you can type into it, resize it, transfer files between Macs and hear the app’s audio, while the app keeps running on its original machine. Beam can also open an entire screen or Mac, according to Shah.

Shah describes the problem through his own setup: some of his Macs run agents and local models, but using an app on one of those machines has usually meant navigating a second desktop through Screen Sharing. In the launch comment, he says Beam works on Apple silicon Macs running macOS Sonoma or later, connecting over a local network or Tailscale. He described it as available to download and free to try for 20 minutes each day.
