Two takes on a thumbnail switcher: AltTab is endlessly configurable; docktor's is rendered in native Liquid Glass.

A switcher that looks like macOS

AltTab is the deeply configurable switcher — custom shortcuts, filters, per-space rules — and if tuning it is the appeal, it’s hard to beat. docktor’s switcher is simpler and rendered in native Liquid Glass, so it feels like part of macOS 26 rather than an overlay. The reason to choose it is the rest of the app around the switcher: hover a Dock icon for live previews, and get music, calendar, weather, and stats beside the Dock.

Frequently asked questions

Can docktor replace AltTab?
For everyday window switching, yes. docktor has a thumbnail switcher that flips between windows across apps. Where AltTab pulls ahead is configuration — if you've spent an afternoon setting up custom shortcuts and per-space filters, you'll miss those.
Is docktor's switcher as configurable as AltTab's?
No, and that's on purpose. docktor ships sensible defaults and a few options; AltTab is built for people who want to tune everything. If tinkering is the appeal, AltTab wins that one.
Then why pick docktor?
Because the switcher isn't all it does. Hover a Dock icon and you get live window previews, and the space by your Dock fills with widgets — music and lyrics, calendar, weather, system stats. AltTab is a switcher; docktor is a switcher that came with the rest.
Are both free?
Yes. AltTab is free and open-source, docktor is free and notarized. Try both and keep whichever you reach for.
