Alt-Tab

About Alt-Tab

Alt-Tab brings the window-switcher experience that Windows users take for granted to macOS. Press Alt+Tab (or your chosen shortcut) and see full live thumbnail previews of every open window across all apps — not just app icons. Navigate with arrow keys, search by window title, minimise or close windows directly from the switcher. Completely free, open source, and configurable with dozens of appearance and behaviour options. One of the most-installed free utilities on Mac.
