Check out AeroSpace. It’s pretty amazing. I’m wondering if it can be made to do things like Niri.

After hopping around MacOS window managers, I landed on Aerospace. For MacOS it's by far the best, and can do most of the things I want.

But it still feels like a plastic fork and knife compared to Niri. Really wish Apple would open up more of their desktop APIs..

Does anybody have experience comparing it with Yabai?

I only tried out Yabai once I discovered AeroSpace in order to compare. I immediately appreciated AeroSpace's take on just completely sidestepping MacOS spaces.

It's not quite the same as Niri, but in case you haven't seen there is _A_ tiling window manager for Mac: Amethyst

No 'endless scrolling' aspect, but I find it works great for managing window sizing and bopping around your windows via keyboard.

there's https://github.com/mogenson/PaperWM.spoon (i haven't tried it)

Should have mentioned that I use Moom at the moment on Mac, and I love it. It's that scrolling paradigm that interests me here though.
