AltTab v11.4.3

Windows-style alt-tab window switching for macOS. See window previews, not just app icons.

macOS Open Source Productivity

AltTab brings proper window switching to macOS. Press alt-tab and see actual window previews with titles, not just app icons. Drag to rearrange, right-click to close or minimize — exactly what Windows and Linux users expect. It's free, open-source, and highly customizable. You can theme it, change the shortcut, and filter which apps appear. Once you install it, the macOS Cmd-Tab behavior feels broken by comparison.
