Comparison
Looking for a Rectangle, Moom, or Magnet alternative?
Those tools are great at what they do — but what they do isn't what Workspaces does. Here's the actual difference, so you can pick the right tool instead of the more familiar one.
The short version
macOS has had Spaces for nearly two decades — and still no way to save them. Rectangle, Moom, and Magnet all solve the same problem: snapping and resizing the window you're currently looking at. None of them remember your setup. That's the gap Workspaces fills.
| Rectangle · Moom · Magnet | Workspaces | |
|---|---|---|
| Snap and resize windows | ✓ | ✓ |
| Save a named setup (which apps, on which desktop, in what position) | ✗ | ✓ |
| Switch between completely different setups in one click | ✗ | ✓ |
| Auto-restore your layout every time you log in | ✗ | ✓ |
When a window snapper is the right tool
If all you need is to quickly size and position the window you're working in right now — left half, right third, full screen — Rectangle, Moom, and Magnet are focused, mature tools built exactly for that. Workspaces isn't trying to out-snap them.
When you need something more
Snapping breaks down the moment your "setup" is bigger than one window. If you switch between a dev environment, a writing environment, and a client-calls environment — each with different apps spread across different Spaces — a snapper makes you rebuild that arrangement by hand, every single time. Workspaces saves the whole thing as a named profile: every app, its Space, and its exact window position. One click restores all of it, and you can set any profile to auto-restore when you log in.
Many people run Workspaces alongside a window snapper — Workspaces handles the big picture (which apps, which Spaces, restored automatically), the snapper handles fine-tuning a single window's size once you're there. See Snap Zones for how Workspaces covers basic snapping too, if you'd rather not run two tools.
Common questions
Is Workspaces a replacement for Rectangle, Moom, or Magnet?
Not exactly — it solves a different problem. Rectangle, Moom, and Magnet snap and resize the window you're currently looking at. Workspaces saves your entire setup as a named profile — which apps are open, which Space each one is on, and where every window sits — and restores all of it in one click. Many users run Workspaces alongside a window snapper.
Can Workspaces snap and resize windows too?
Yes. Workspaces includes snap zones (drag a window to a pin for a clean split, third, or full-screen placement), so you don't need to run a separate snapping tool just for that. But its main job — saving and restoring a whole setup — is the part Rectangle, Moom, and Magnet don't do at all.
Does Workspaces auto-restore my layout when I log in?
Yes. You can set any saved profile as your login default, and Workspaces restores it automatically every time you log in — no window snapper does this, since none of them save a full setup to restore in the first place.
