eternal is better than mosh https://eternalterminal.dev/
Right there, Eternal doesn't even try to cover the same use case as Mosh. It might be an alternative, same way regular SSH is an alternative, but there's no way it can be "better"
I have used Mosh for years and recently heard of ET, but when I tried it I experienced noticeable hangs that I don’t get with Mosh, and I went back.
I heard from several people that “ET is the new Mosh”, but it won’t be for me unless I can figure out/resolve those hangs
> While mosh provides the same core functionality as ET, it does not support native scrolling nor tmux control mode (tmux -CC).
