Does Magnet save window layouts?
Magnet snaps individual windows into halves, thirds and quarters. It does not save a multi-app arrangement across Spaces and displays, relaunch apps or reopen browser tabs.
Alternative
Short answer: Magnet places one window at a time and does not remember the arrangement. SnapState saves the full setup, apps, windows on every Space, displays and browser tabs, and restores it in one click or automatically on wake and monitor connect. $9.99 one-time for up to three Macs.
Magnet moves the frontmost window into a snap area when you drag it to an edge or press a shortcut. That is all it remembers. It does not keep a record of where all your windows were, so after sleep, a restart, a macOS update or plugging into a dock you start from a messy screen and rebuild the layout window by window. It does not relaunch apps, put apps back on their Spaces, handle full screen windows or reopen browser tabs.
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.
The two run fine side by side: snap with Magnet while you work, save the result as a SnapState workspace, and let SnapState put it back. See also Rectangle, Magnet and Raycast vs SnapState and Moom vs Magnet.

macOS re-detects displays on wake and reconnect and often piles windows onto one screen. Magnet has nothing saved to put back, so you snap each window again. SnapState can restore the saved workspace automatically on wake or when a monitor connects.
Yes. Magnet snaps while you work, SnapState saves the result and restores it.
