ClutterFreeMac vs Rectangle

Rectangle snaps a window into a slot when you ask. ClutterFreeMac arranges every window, all the time. Which one fits how you work, and when to use both.

Compare · Updated 12 October 2026

Rectangle is a free, open source app that moves and resizes the front window with keyboard shortcuts or by dragging it to snap areas at the screen edges. It is excellent at what it does, and lots of people should keep using it.

The difference in one line

Rectangle puts one window where you tell it. ClutterFreeMac decides where every window goes, and keeps them there.
