SizeUp
Powerful, keyboard-centric window management.
SizeUp enables rapid resizing and positioning of windows on macOS using keyboard shortcuts or a menu‑bar icon. It offers predefined actions that move the frontmost window to the left, right, top, or bottom half of the screen, as well as quarter‑screen quadrants, facilitating side‑by‑side comparisons and file management. The tool also supports moving windows between monitors and Spaces, and provides a full‑screen mode that differs from the standard green button.
Additional features include configurable margins to preserve space at screen edges, a SnapBack function that restores a window’s previous size and location, and AppleScript integration for creating custom actions such as three‑column layouts or edge‑anchored placements. All actions can be invoked with user‑defined global shortcuts, allowing consistent control across any application.
The software targets users who juggle multiple windows and seek a keyboard‑centric workflow to improve screen‑real‑estate efficiency on macOS 10.6 and later, including macOS 14 Sonoma.
