Magnet is a window manager for Mac that snaps windows into organized tiles. It's for anyone who works with several apps side by side and wants to arrange them without resizing by hand.

Key features:

Drag a window to a corner to snap it into a quarter, or to a side edge for a half.
Drag to the top edge to maximize, or to the bottom edge for thirds, sliding along it to expand to two thirds.
Arrange windows with customizable keyboard shortcuts, the menu bar icon, or the green button menu.
Create your own custom commands and adjust layout properties.
Use it on up to six external displays, including vertical screens.
Sync settings through iCloud.

Magnet is sold on the Mac App Store for $4.99 and requires macOS 13 or later. It's a perpetual license with free updates, no subscription, no in-app purchases, and no personal data collection.
