The beauty of river is that you just get to try out WMs :)

I use river and pair it with kwm. Not sure about their LLM policy, but I don't see any gregarious signs of usage in the repo: https://github.com/kewuaa/kwm.

Would recommend to anyone coming from dwm.

I was not aware of that repo existing, that's a pretty cool resource to have. Unfortunately i haven't tried any of the river window managers yet. My distro only has the old river still and i haven't bothered packaging anything myself (yet), but i am curious what the experience is like.

I used river for quite some time when I moved over to Wayland from bspwm. I still find it great for configuring from scratch.

No idea what are beansprout and rhine though.
