I find HyperSwitch to be better more useful interface compared to Witch, because it retains the whole thumbnails look:

https://bahoom.com/hyperswitch

Its developer hasn't been updating it or fixing bugs for a long time now, but it remains the best 'alt-tab' for macOS in my book.

https://alt-tab-macos.netlify.app/ Is an open source alternative with thumbnails. I don’t care about them so I stick with Contexts.co, but this is my back up

Great app but it's pretty buggy. command+tab to an app that has multiple windwos and then command + window number crashes for me, which seems like one of the primary features. Seems like alt+tab directly to the window works though.

I tried the open source https://alt-tab-macos.netlify.app which mentions HyperSwitch among others. It was fine. Though I only tested it briefly.

Awesome! Finally some alternatives! I'll try it and switch to that GPL project if it's a better app! Thanks for sharing. Update: AltTab is already better and exactly what one wants from an alt-tab, and best of all, FOSS and actively in development on Github. It's got some small bugs to iron out but none that are dealbreakers for me. PERFECT, thank you.

That is awesome! I didn’t try it yet. Just saw the nice vibe of creator and the license. Glad you like it.

Trying to soon foray into consulting/coaching including [productivity enhancing] apps and workflows. This is a nice boost before going to sleep.

I switched to https://contexts.co/ after many years with Witch. Have never looked back. Contexts is much better in my opinion.
