I believe the developers have been working on a new version on EE that includes a GUI.
Apparently there's been pretty signifcant delays https://twitter.com/easyengine/status/835455801816977408 and the future seems a bit uncertain.
In general, their lack of communication (other than twitter) is very disappointing.
I've also been looking at other alternatives. Trellis seems to be a bit more involved than I currently want to get involved with. There are also issues setting up on windows https://discourse.roots.io/t/where-can-i-find-a-complete-tutorial-for-windows-trellis-sage/7049
Personally been looking into stuff like Centmin Mod (Centos LEMP Stack script) https://centminmod.com/
and AnisPress (a former EE contributor) https://ansipress.github.io/
