Rectangle

Snap windows to halves, thirds and corners

MacFree, open source

The verdict

Free and open source, Rectangle snaps Mac windows to halves, thirds and corners with a keyboard shortcut or a drag to the screen edge, and pressing the shortcut again cycles through sizes. A Tile All action spreads every open window across the screen at once. Magnet charges $4.99 for the same basic snapping, and the only catch here is that version 2 needs macOS 14 or later, with 1.100 kept for older Macs.
