Moom vs Magnet: snapping, layouts, and the gap.

Magnet

Magnet is a Mac App Store snapping tool: drag a window to an edge or use a shortcut to fill halves, thirds and quarters. It is easy and cheap, and it does not save multi-window layouts.

Moom

Moom snaps and resizes with a hover palette and grid, and can save window arrangements and trigger them on display changes. It is more powerful and takes more setup. See Moom vs SnapState.

What neither does

Neither relaunches your apps with a saved layout, reopens browser tabs, or puts apps back on the Space they were on. That is the job SnapState does.

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.

What are the honest limits?

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.
