Rectangle

About

Rectangle is a free, open source Mac app for moving and resizing windows in macOS. You can use keyboard shortcuts, or drag a window to a screen edge or corner to snap it into place. Portrait display layouts are supported too. Repeating a shortcut cycles a window through different sizes, so you have fewer shortcuts to memorize.

Rectangle is nearly a complete drop-in replacement for Spectacle, and you can select Spectacle's default shortcuts when the app first runs. It supports macOS 14 and later.

For more, Rectangle Pro offers quicker window snapping and custom shortcuts for any size and position. Rectangle is also available as part of a suite that includes Multitouch, which adds gesture support.
