Beam

Your other Mac's windows, on this Mac

FreemiummacOS

Beam brings a single app window from another Mac onto the Mac in front of you — with its own Dock icon and a place in Cmd-Tab — instead of handing you a picture of a whole desktop. Windows travel straight from Mac to Mac, encrypted, never through Beam's servers, and headless Mac minis and Studios list their windows too. You can beam several windows at once, move files between Macs, or share one window in any browser via a link. Hosting Macs is free; using your other Macs costs 20 free minutes a day, then $84 a year or $199 once for a lifetime licence. It launched on Product Hunt on 18 October 2026.
