Mosaic

About

Mosaic lets you resize and re-position windows on your Mac with a simple drag and drop, and it is integrated into macOS. When you drag an app window, Mosaic displays a panel of Layouts. To apply one, drag the window onto a Layout and drop it. Power users can also use Shortcut Keys and TouchBar support.

Mosaic includes Basic and Advanced Layouts, and you can create your own. Quick Layout lets you define a single-use Layout by dragging on a grid. You can adjust the space around windows, the Layout panel activation, and the grid sizes. Mosaic also supports multiple monitors, Layout Views, and Groups for switching between sets of Layouts. Auto Layout remembers where you want each app window and applies the correct Layout. Quick Positions moves a window to a screen edge, corner, or center, and Window Capture takes a screen capture of a window.

Mosaic is compatible with macOS 26 Tahoe and requires macOS 10.13 or higher. A free 7-day trial is available. The Mosaic Remote companion app, available on the App Store, lets you apply a layout to the active window from an iPhone or iPad.
