Beam walks one window off your agents' Mac mini and leaves a note saying where it went
Beam pulls a single app window from a headless Mac mini, the one running your builds and agents, onto the Mac at your desk as a native window with its own Dock icon.
The Mac mini in the closet has no monitor, no keyboard and a job: builds, agents, whatever you don’t want spinning fans on your desk. Beam lets you reach in and take one window off it. “The build on the Studio. The agents on the Mac mini,” the site says, and each of those can show up on your desk Mac as its own window.
It’s a real window, too, and that changes how it feels. It sits “in your ⌘Tab with its own Dock icon,” you can drag a file onto it, and “Drag a corner here and the real window resizes over there.” Beam’s own walkthrough for a headless mini puts the agent case plainly: “Pick the browser the agent is driving and watch it work.”
Beam can leave the window where it is, so anyone at the other Mac still sees it, or move it over entirely. “Bring a window over completely. It leaves the other Mac’s screen, and a small note there says where it went.” The site’s own description: “Like the app walked across the room.”
Play the video on YouTubeThe mini doesn’t even need a screen for any of this. Beam “gives the mini a virtual one on its behalf, at Retina density,” and the walkthrough warns that full-screen apps and apps with custom window chrome may act differently on that virtual display than on a real one. Beam is made by Noats, the company behind a meeting notepad for the Mac. It can’t cross networks on its own: the privacy post says two Macs on different networks with no shared tailnet can’t reach each other, and the walkthrough’s answer for a mini somewhere else is Tailscale on both Macs.
Agent work tends to get watched more than touched: a browser being driven, a test run scrolling, a terminal waiting for a yes. Tools built around one window at a time fit that rhythm better than tools built around taking over a whole desktop, and more of them are likely as more people park a second Mac somewhere and let it work. The open question is what happens when there are five agents on that mini, each with its own browser, and all of them want a spot in your ⌘Tab.
Trying it costs nothing for a while. The free plan gives “20 minutes a day of everything,” according to the pricing page, and unlimited use runs $84 a year or “$199 once for Lifetime.” It needs “Two Macs on macOS Sonoma or later, Apple silicon or Intel, with Beam on both.”
