About AltTab Pro

AltTab Pro brings the powerful, intuitive window-switching functionality of Windows to the Mac ecosystem, complete with an elegant look and highly customizable upgrades.

While the core app remains a free and open-source tool providing lightning-fast window switching with high-quality thumbnails, the Pro version elevates the experience for power users with four major upgrades:

  • App Icons & Window Titles Styles: Switch seamlessly between three appearance modes—live window thumbnails, a clean dock-like icon view, or a compact text-only list.
  • Instant Search: Find any window immediately just by typing its title or application name.
  • Auto-Sizing Switcher: Thumbnails automatically scale based on your workspace clutter—expanding when you have fewer windows and shrinking to fit when you have many.
  • Multiple Shortcuts: Configure up to 9 independent keyboard shortcuts, each with custom keys and specific window filters.
