## Kitsmith's take

The default free pick for seeing every open window at a glance, not just cycling app icons: AltTab shows live thumbnails of every window (grouped or flat), with Dark Mode, trackpad gestures, and up to 9 independently configurable keyboard shortcuts. Built and maintained since 2016 by a developer using the handle lwouis (no full name publicly disclosed on the project’s site or GitHub profile) — 8.6M downloads and 16k GitHub stars, with press mentions from MacRumors, How-To Geek, and Lifehacker. The core switching experience stays free and open source under the plain “AltTab” name most people search for; the developer now also markets an optional “AltTab Pro” upgrade ($9.99 one-time or $24.99 lifetime) that adds in-switcher search, two extra display styles, and auto-sizing thumbnails.

## Features

- **Live window thumbnails:** See every open window as a real preview, not just an app icon, with multiple display styles to choose from.
- **Up to 9 custom shortcuts:** Pro tier: configure independent keyboard shortcuts, each with its own filters and appearance (Free tier ships one).
- **Trackpad and Dark Mode support:** Full trackpad gesture support and native Dark Mode, included free.

## FAQ

**Is AltTab free?**

The core window switcher is free and open source. An optional Pro upgrade ($9.99 one-time or $24.99 lifetime, 14-day trial) adds search, extra styles, and more shortcuts.

**Who makes AltTab?**

A developer using the GitHub handle lwouis; no full name is publicly disclosed on the project’s site or GitHub profile.

**Is AltTab the same as “AltTab Pro”?**

Yes — the developer now markets the project under the “AltTab Pro” name on its homepage, but the underlying open-source app (Homebrew cask alt-tab, GitHub repo alt-tab-macos) is the same AltTab most people search for, with Pro as an optional paid layer on top.
