What is Rectangle?

Rectangle is a free and open source window management utility for macOS that lets users move and resize windows using keyboard shortcuts or by dragging them to screen edges and corners to snap into place. It supports cycling through multiple window sizes by repeating a shortcut, and works with portrait display orientations for vertical monitor setups. The free version covers the core snapping and shortcut functionality, while Rectangle Pro unlocks quicker window snapping and custom shortcuts for any size and position, sold as a subscription with a 10-day free trial and support for up to three devices per license. Rectangle runs natively on both Intel and Apple Silicon Macs running macOS 10.15 or later, and is built as a near drop-in replacement for the discontinued Spectacle app.

Magnet

AI-suggested

Magnet is a lightweight macOS window manager from CrowdCafe that lets users drag a window to the edge or corner of the screen to snap it into a half, quarter, or third of the display. It can also be controlled from the menu bar or with customizable keyboard shortcuts, and supports layouts for fullscreen, halves, thirds, and corner quarters. The app targets people who juggle multiple windows and want faster, more consistent arrangement than manual dragging and resizing. It is a simple, focused, one-time-purchase utility rather than a full automation suite.

Moom

AI-suggested

Moom is a macOS window management utility from Many Tricks that adds fast ways to move and resize windows beyond macOS's built-in options. Hovering over a window's zoom button (or using a hotkey) pops up a customizable palette of up to 61 positioning actions, letting users snap a window to halves, quarters, or custom grid positions in a click or two. Beyond one-off positioning, Moom can save entire window layouts and restore them later, chain multiple actions together, and be operated entirely from the keyboard. It is a one-time purchase for macOS 10.13 and newer, with a free trial available before buying, and has been maintained by Many Tricks for many years with continued updates.
