Moom is a window manager for Mac that makes moving and resizing windows fast. It works with the mouse or entirely from the keyboard.

Key features:

Hover over a window's green button to open a pop-up palette with up to 61 actions.
Save window layouts and restore them, including layouts for whichever windows you used most recently.
Drag windows to snap zones, or drop them into positions from a saved layout.
Chain actions together, for example to move a window to another display and resize it in one step.
Move and resize the window under the pointer by holding modifier keys.
Move, resize and center windows from the keyboard with an on-screen grid and controller.
Export and import your custom actions to share setups between Macs.

Moom 4.6 requires macOS 10.13 High Sierra or newer. You can try it for free, and owners of Moom 3 (Classic) can upgrade at a discount. Moom Classic is still available on the Mac App Store.
