Obra Window Utility

Snap the frontmost window left, right, or full screen. A small menu bar app that does three things and nothing else.

Three shortcuts

Send window left ⌃⌥⌘←
Send window right ⌃⌥⌘→
Make window full screen⌃⌥⌘M

The defaults match SizeUp's, so muscle memory carries over. All three can be rebound or cleared in Settings.

On first launch

macOS only lets an app move other apps' windows once you allow it in System Settings › Privacy & Security › Accessibility. Obra Window Utility asks the first time you run it. That grant is the only permission it ever needs — it has no network access and stores nothing but your shortcut preferences.
