About
Loop rethinks window management around a radial menu: hold a trigger key, flick the cursor in a direction, and the frontmost window snaps to that half, quarter or custom position of the screen. A live preview shows each resize before it lands, keyboard shortcuts cover every action for those who prefer keys, and a stash tucks windows away at the screen edges until they are needed again.
Built by Kai (MrKai77) and licensed under GPL-3.0, Loop is free, open source and endlessly customisable, with themeable colours for the radial menu and more than 11,000 stars on GitHub. Version 1.4.2 arrived in January 2026, and the app supports macOS 13 and later, with scripting through a URL scheme and AppleScript. Few utilities make a daily chore this genuinely pleasant.
Alternatives
- Rectangle
Pick Rectangle if your Mac is older than Ventura: it is free and open source, supports macOS 10.15 and later on Intel and Apple silicon, and snaps by shortcut or drag.
- Magnet
Pick Magnet if you would rather buy a simple snapper from the Mac App Store: it is $4.99, snaps windows into halves, quarters and thirds, and needs macOS 13 or later.
- macOS Window Tiling
Stay with macOS window tiling if you only need basic snapping: from macOS Sequoia it is built in and free, with drag-to-edge, the green button and keyboard shortcuts.

Curator's Note
“The radial menu turns a daily chore into something you catch yourself doing for fun.”
