ChainYourMac

ChainYourMac is a window manager for macOS built around a single idea: instead of stacking windows on top of each other, it arranges them side by side along one endless horizontal strip. Opening another app extends the strip rather than shrinking existing windows, and you navigate by scrolling. The approach mirrors PaperWM and niri on Linux, but is implemented natively for the Mac.

The app centers on trackpad swiping and keyboard control. Shortcuts cover focusing left and right, moving windows, cycling or forcing full width, centering, stacking and popping out of stacks, plus tab handling and dimming inactive windows. Version 2.3 adds column pinning. The site hosts a working interactive demo, not a video, where you can drag title bars, open apps from the Dock and close windows to feel the model.

It is aimed at Mac users who keep many windows open and dislike overlapping or hidden windows, especially developers and others who work across terminals, editors and browsers at once. Because it is distributed as a notarized and Developer ID-signed app with no account and no in-app telemetry, it also suits people who prefer minimal setup and data collection.

Before buying, try the on-page demo and check the setup and FAQ sections, since the app needs Accessibility permission. The license is a one-time $19.99 purchase for lifetime use, and the app requires macOS 13 or later on Apple silicon. Overall, it is a focused alternative for Mac users who want a scrolling tiling workflow wit
