Looks like it's available under msys2 on windows: https://packages.msys2.org/base/mosh
As an aside: msys2 mingw64 and friends are > 100 hours saved if you are a linux-soul in a windows environment. I don't think msys gets the attention it deserves.
I keep one laptop at home and one laptop at work and can seamlessly switch between the two without having to manage my active sessions at all. If I open a new tab at work and go home for the day it'll be there on my laptop at home.
Mosh using UDP means that as a connectionless protocol, your end points can move (eg: from WiFi to LTE, or vice-versa), and beyond a small hiccup, your connections remain alive and well.
If you are mostly on unreliable and high-latency connections, mosh will likely feel better, but with no native scrollback.
