Windows support via real ConPTY without WSL

- The maker's post
windows support + async + public sdk. You can rewrite zellij with rmux, but not the opposite. rmux is a multiplexer engine

Programmable SDK with async wait-until primitives
From 2 comments
windows support, and the sdk. native async "wait until" something appears on your terminal, so you don't spam send-keys

Objections
Website looks AI-generated
From 2 comments
The website is a little too obviously made by Claude. The first thing I noticed is the classic "pill with pulsing green dot that says something is active or live" claudism.

Unclear what it adds over tmux with send-keys
From 3 comments
I found the project quite interesting but what's the advantage over just using tmux with a hotkey to send keys?
luizfwolf on HNIt's not clear to me what this does that `tmux` doesn't? Agents can already interact with `tmux`, so what does this provide?
SwellJoe on HNNever had the need to do playwright automation for tmux, so not sure why I would use this above tmux which works well.

kosolam on HNI don't get it as well, everything mentioned in the readme is already trivially possible with tmux or zellij
