LanesMac

LanesMac is a scrolling window manager for macOS. Instead of shrinking every open window into the same screen or stacking them on top of each other, it places each window as a full-height column on one long horizontal strip. Your display shows part of that strip, and moving focus slides it to the window you need. New windows open beside the one you are using, and each column keeps its width when you open more apps.

The app adds stacks that group two to five related windows in one column, tabbed columns, pinned columns for chat or music at the screen edge, and a separate strip for each display. You can move and resize windows with keyboard shortcuts, the mouse or trackpad swipes, and the lanesmac command-line tool and lanesmac:// links can focus windows, save and load layouts, and flag a column when a long job finishes. Layouts are restored after a restart or sleep.

LanesMac is built for Mac users who already like tiling or scrolling layouts from Linux, such as PaperWM or niri, and want a native settings window instead of a config file. It requires macOS 13 Ventura or later on Apple silicon or Intel Macs and asks only for the Accessibility permission. The site says it has no account, no analytics and no tracking.
