Ecosystem overview for everything related to alt-tab.
AltTab is a highly popular macOS productivity tool that brings the classic Windows Alt-Tab window-switching experience to Mac. Unlike the native macOS switcher, which only cycles between applications, AltTab enables users to seamlessly switch between individual windows across all open apps. It drastically improves multitasking by displaying live window thumbnails and offering extensive customization. Features include multiple layout styles, configurable keyboard shortcuts, multi-monitor support, and Spaces integration. Recently shifting to a freemium model with a Pro tier, AltTab continues to be an essential workflow enhancement for power users and those transitioning from Windows.
