AltTab

What it is for

AltTab is a Windows-style window switcher for Mac: you hold the shortcut, pick among live thumbnails (even two windows of the same app), and the core is Free OSS. Use it when the job is a switch you start at a public $, not when you need Magnet’s $4.99 snap only.

Soft-note: Free OSS core (GPL-3.0) at lwouis/alt-tab-macos + AltTab Pro $9.99 (current major) or Pro Lifetime $24.99 + 14-day Pro trial. Distinct from Magnet, Rectangle, and Raycast.

What makes it unique: the cover is AltTab’s official switcher thumbnails (MacBook with Japan itinerary / Trip checklist / Weekend recipes live previews) from the homepage still — not a wordmark. Soft-note: homepage marketing frame (“Find the right window”), real switcher chrome. The three window thumbnails themselves are ops of the switcher.

Key features

• Live thumbnails — Japan itinerary / Trip checklist / Weekend recipes on the cover (cover still; product). One desk. Cover ramen / checklist sit here.
• Windows of the same app — every window, not just every app (product; pricing). A window, not a Pro tile.
• Full-size preview — the selected window comes forward before you switch (product). A preview, not a $9.99 meter.
• Spaces + screens — minimized, hidden, other Space (product). A space, not Get started.
• Pro Search — type a title or app name (pricing). Search, not the free default.
• Pro Styles — thumbnails / app icons / compact titles (pricing). A style, not SSO.

Download / Buy Pro are CTAs (not desks). Free / Pro $ stay in Pricing. There is no AI extra to drop.

Who it's for

Best fit: Mac users on macOS 12+ who will stay on Free OSS while they switch a first same-app window — then Pro at $9.99 (current major) when they want Search / extra styles, not Magnet $4.99 first unless they want snap tiles.

Pricing

Verified 2026-10-23 (Asia/Shanghai) from alt-tab.app/pricing plus alt-tab.app and github.com/lwouis/alt-tab-macos (LICENCE.md GPL-3.0; SPDX GPL-3.0). Soft-note: Pro is a license on the signed binary; source stays GPL.

Alternatives

• Magnet — an App Store snap when you want $4.99 tiles, not live window thumbnails.

• Raycast — a launcher + window commands when you want Free $0 / Pro $10, not a Windows-style thumbnail switcher.
