Beam.win: Run AI agents on one Mac and use its windows on another

Hiten Shah and Sam Asante debuted the app on October 19 through their company, Noats. It requires Apple Silicon and macOS Sonoma or later on both machines, connecting over Wi-Fi or Tailscale. Traffic avoids the vendor: Windows, keystrokes, clipboard, and audio travel directly between the two Macs, encrypted, without passing through Beam's servers. Pricing is split by role. Hosting a Mac and joining a share link are free. Using your own Mac to pull windows from another is free for 20 minutes a day, after which it costs $12 a month, $84 a year, or $199 for a lifetime license. Most remote access tools show an entire desktop. Alternatives like Jump Desktop, Screens, and Apple's Screen Sharing mirror the whole screen instead. Beam instead lifts one application window, and the window gets its own Dock icon, responds to Command+Tab, resizes in place, and supports dragging files and local audio playback. If a single window is not enough, Beam can pull over a full display or the whole Mac. For a founder running agents on a headless Mac mini, the appeal is less context switching: a terminal or browser session the agent is working in can sit beside local apps without a second desktop. The limits are hardware and platform scope, since the app only runs on macOS, and whether per-window access beats full-screen sharing in multi-Mac setups remains unproven. Teams that already run local models or build machines on Macs should weigh the free tier against the cost of keeping those jobs visible.
