AltTab review
A free, open-source Mac window switcher with previews, search, and customizable shortcuts.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
AltTab is a macOS utility for switching among open windows, aimed at people who want a visual alternative to cycling through app icons. Its switcher can show high-quality thumbnails and live previews, and users can choose thumbnail, app-icon, or window-title styles. The core product is free and open source, making it relevant to solo users and small teams looking for a desktop window switcher rather than a cross-platform or browser-tab tool.
The feature split is straightforward: the free tier covers core window switching, while Pro adds search by typing, additional appearance styles, automatic thumbnail sizing, and up to nine keyboard shortcuts. Pro includes updates for the current major version; Pro Lifetime includes all Pro features and every future update. A 14-day free trial and 30-day refund period are also listed. This structure suits someone who wants to try the paid controls before deciding, while people content with the core switcher can stay on the free version.
AltTab’s focus is visual navigation and control: it can resize thumbnails to fit the number of windows, and it supports window controls and trackpad gestures. It is limited to macOS and does not switch browser tabs, so it is not a fit for users seeking a Windows option or a unified app-and-tab switcher. Choose it if previews, searchable windows, and shortcut customization matter on a Mac; consider another tool if broader platform coverage or browser-tab switching is central to your workflow.
