Privacy and respecting the user

AltTab doesn’t upload or download any data without the user explicitly asking for it (e.g. asking to update the app, sending a crash report, etc)
AltTab uses as few resources as possible: CPU, memory, disk, etc. The app footprint is small (e.g. small disk size, minimal CPU use in the background, etc)

Configuration

Change the shortcut keys, switch to a Windows theme and more, using the Preferences window:

Alternatives

Before building my own app, I looked around at similar apps. However, none was completely satisfactory so I rolled my own. Also, the almost-good-enough apps are not open-source.

Alternative	Differences
HyperSwitch and HyperDock	$10. Closed-source. Thumbnails are too small. App icon is on top of the thumbnail
WindowSwitcher	$7. Closed-source. Thumbnails are small and blurry. App icon is on top of the thumbnail
Switch	Open Source. Thumbnails are small. Very little customization. Latest release is from 2016
Witch and Contexts	$10-15. Closed-source. Focus on text. No thumbnails
MissionControl Plus	$10. Closed-source. No chronology and order to windows. Hard to navigate windows with keyboard
Built-in MissionControl	No keyboard support
Built-in `⌘ command` + `⇥ tab`	Only shows apps, not windows (note: can press down to see window of selected app)
Built-in `⌘ command` + `	Cycles through tabs and windows, but only of the same app. Only cycling, no direct access

There are also related apps which don’t really overlap in functionality, but target similar needs: Swish, Hookshot, Magnet, Spectacle, Rectangle, yabai, LayAuto, OptimalLayout, BetterTouchTool, BetterSnapTool, Moom, uBar.
