Best Window Management Apps for Mac (2026)
The best window manager for most Mac users is Rectangle — a free, open-source app that snaps windows with keyboard shortcuts. Amethyst and AeroSpace add automatic tiling for keyboard-first power users, and Magnet is the polished paid pick. All install via Homebrew.
How we pick: apps are ranked on Homebrew availability, active maintenance, pricing, and category fit. Our methodology.
How to choose
- Snapping vs. automatic tiling. Snappers (Rectangle, Magnet) move one window when you ask; tiling managers (Amethyst, AeroSpace) continuously arrange every window into a grid. Tiling is powerful but changes how your whole desktop behaves.
- Keyboard vs. mouse workflow. If you want to arrange windows without touching the mouse, prioritize configurable shortcuts (all four picks); if you prefer dragging to screen edges, Rectangle and Magnet do that best.
- Open source vs. paid polish. Rectangle, Amethyst, and AeroSpace are free and open source; Magnet is a small one-time App Store purchase with a very gentle learning curve.

If you work mostly in one full-screen app at a time — or macOS Spaces and the green-button tiling already cover your splits — a window manager will not change your day. It shines on large or multiple monitors with many windows in play.
