Rectangle is a free, open-source window management application for macOS, written in Swift. It lets users snap, resize, and reposition windows instantly using keyboard shortcuts or by dragging windows to screen edges. Built as the spiritual successor to the popular Spectacle app, Rectangle has become the go-to window manager for Mac users who want Windows-style snapping without paying for it.

Key Features

Window Snapping to halves, thirds, quarters, sixths, and full-screen layouts.
Customizable Keyboard Shortcuts for every window position and size.
Drag-to-Snap by dragging windows to screen edges or corners.
Multi-Monitor Support for moving windows across displays.
Cycle Through Sizes by repeating the same shortcut to resize incrementally.
Rectangle Pro (paid upgrade) for gap settings, custom snap areas, window layouts, and more.

Why Choose Rectangle?

Rectangle is designed for Mac users who miss the snap-to-edge window management that Windows offers natively. It runs quietly in the background, consumes minimal system resources, and requires no account or configuration to get started. The free tier covers nearly everything most users need, while Rectangle Pro adds advanced layout controls for power users.

Whether you're a developer, designer, writer, or everyday Mac user, Rectangle is widely considered a must-install utility.
