Comparison

Superdock vs AltTab

By Mahad Kazmi, developer of Superdock. Updated 3 September 2026.

Short answer. AltTab does one thing: a Windows-style switcher that lists every window with a live thumbnail. Choose Superdock if you want the switcher and a Dock that separates Chrome profiles, previews windows on hover, runs on every display and keeps Tahoe windows above the dock.

AltTab does one thing: a Windows-style switcher that lists every window with a live thumbnail. Superdock includes a window switcher as one part of a full Dock replacement. If you only want the switcher, AltTab is the smaller install.

Choose AltTab if

You want only a switcher, you want it free and open source, or you want AltTab Pro's typed search across windows.

Choose Superdock if

You want the switcher and a Dock that separates Chrome profiles, previews windows on hover, runs on every display and keeps Tahoe windows above the dock. Superdock's switcher labels Chrome windows by profile, which AltTab cannot know.

Try both

Superdock is free to download and the Chrome profile icons are free for 14 days. Run one dock at a time: two apps watching windows at once can freeze the desktop.
