Lasso

Lasso provides a grid‑based interface for arranging windows on macOS, letting users move and resize windows with mouse or keyboard actions. The grid system is designed to be intuitive: clicking and dragging a window’s edge or holding a modifier key adjusts its size and position without requiring precise manual placement. It also supports multiple monitors, automatically handling window placement across any number of displays.

Users can define and store custom window layouts, assigning each layout a global keyboard shortcut for rapid activation. Layouts can be exported and imported, facilitating sharing or backup of preferred arrangements. Preferences are synchronized through iCloud, allowing the same configuration to be used on different macOS devices.

The interface is customizable, and the app includes pre‑configured layouts and shortcuts that emulate other popular window managers, easing the transition for new users. Lasso is positioned as a stable utility for macOS 13 and later.
