Mac window manager for saved layouts, not tiling.

A Mac window manager can mean two jobs: snapping the front window, or restoring a layout you already made. SnapState does the second job. It saves windows on every Space, the apps needed to relaunch them, the display layout, and all open tabs in supported browsers, then restores that named workspace from the menu bar.

How do you save a Mac window layout?

1. Arrange your work. Put your editor, browser, terminal, calls, or research windows where you want them.
2. Capture from the menu bar. Give the setup a name. SnapState stores the windows on every Space and the apps behind them on your Mac.
3. Restore the context. Choose the workspace or press a shortcut. SnapState launches what is missing and puts the windows back.

What does SnapState remember?

• Visible app windows on the current macOS desktop, including their position and size.
• The apps needed to relaunch a saved workspace.
• Which display each window was using and the saved display topology.
• All open tabs from supported browser windows after Automation permission is granted.
• Optional reactions to display connect, disconnect, matching-layout, and wake-from-sleep events.

How is this different from window tiling?

A tiling app helps you place the window you are using right now. SnapState is for a different job: preserving a complete arrangement you already made and calling it back later. That makes it useful for separate coding, design, writing, meeting, or research setups without rebuilding each one by hand. For a closer look at that trade-off, see the Moom vs SnapState comparison.

Which Macs does SnapState support?

The current shipped build is for Apple Silicon and Intel Macs running macOS 15.7 or later. SnapState is distributed directly as a signed and notarized DMG rather than through the Mac App Store because it uses Accessibility and Apple Events to manage windows and browser context.

What does SnapState not save?

The current release restores all open tabs in each supported browser window, not every tab group. It also restores layouts across multiple Spaces (apps go back to the Space they were saved on, full-screen windows return to full screen, and windows on other Spaces are placed when you switch to them).
