Does Rectangle save window layouts?
The free Rectangle snaps individual windows and does not save multi-app layouts across Spaces.
Alternative
Short answer: Keep Rectangle for snapping. Add SnapState to save the full arrangement, apps, Spaces, displays and browser tabs, and restore it in one click or automatically. $9.99 one-time for up to three Macs.
Rectangle is a free, open source window snapping app. Keyboard shortcuts and dragging to screen edges move the frontmost window into halves, thirds, quarters and more. It is fast and simple.
Rectangle acts on one window at a time. It does not remember where all your windows were, relaunch apps, put apps back on their Spaces or reopen browser tabs, so after sleep, a restart or plugging into a monitor you snap everything again. The paid Rectangle Pro adds more features, and it is still a snapping tool at heart.
SnapState is a native macOS menu bar app that saves named workspaces. Each one keeps the windows on every Space with position and size, the apps needed to relaunch them, the display layout, full screen windows, and all open tabs in Safari, Chrome, Edge, Brave, Arc and Chromium once Automation permission is granted. Restore from the menu bar, with Control-Command-1 to 6, or automatically on wake from sleep, when a monitor connects or disconnects, or when a matching display layout appears.
They do different jobs and run fine side by side: snap with Rectangle while you work, save the result as a SnapState workspace, and let SnapState put it back. See also Rectangle, Magnet and Raycast vs SnapState.
SnapState does not tile or snap windows, it cannot split one app's windows across several Spaces, Firefox is not supported yet, tab groups are not restored, and it requires macOS 15.7 or later. There is no free trial.
