The original
DockDoor
Shows window previews when hovering macOS Dock icons, plus an Alt-Tab switcher.
Replacements
Listings that take over the same core job as DockDoor.
AltTab
Brings the Windows-style Alt-Tab window switcher to macOS.
AltTab replaces only the switcher part with live window thumbnails and extensive keyboard customisation, without Dock icon previews, and has no separately sold Pro version.
Witch
A macOS switcher that moves between individual windows and tabs, not just applications.
Witch switches between individual windows and tabs with several configurable switcher layouts, but it is paid after the trial, closed source and has no Dock previews.
Contexts
A Mac window switcher with fuzzy search, a sidebar, gestures and a replacement Command-Tab.
Contexts adds fuzzy search by app name or window title, a sidebar and gestures to window switching, but it is closed source and paid after the trial.
