Rectangle is a free, open-source window manager for macOS. It moves and resizes windows through keyboard shortcuts or snap areas, making repeatable layouts faster than manually dragging window edges into place.

Send a window to the left or right half of a screen, place it in a corner, center it, maximize it, or use a proportion that suits a particular display. This is useful when a browser, document, terminal, chat window, and reference material need consistent positions across a normal workday.

Rectangle changes window geometry rather than replacing the apps in those windows. Its value comes from learning a few layouts that match the work, while checking for conflicts with macOS shortcuts or another window manager before enabling overlapping controls.

Features

Move and resize windows with keyboard shortcuts or configurable snap areas.
Place windows in common layouts including halves, corners, thirds, center, and maximize.
Use a free, open-source utility that supports both Apple Silicon and Intel Macs running supported macOS versions.
Configure window-management behavior around a personal set of repeated layouts.
Upgrade separately to Rectangle Pro only if custom positions and its additional workflow features are needed.

Where it fits

Rectangle fits people who repeatedly arrange two or more windows and want a lightweight keyboard-first way to do it. It is a natural companion for large displays, external monitors, or focused split-screen work.

It is unnecessary when macOS’s built-in tiling is sufficient. Keep its shortcuts small and memorable, especially when using other productivity tools that reserve the same key combinations.
