Anyone used VX?

went on the core’s ressources site to see what’s new (and what outdated links haven’t yet been removed) and came upon VX.
Never heard of it before, but it looks interesting(for lack of a better word).
Curious if anyone used it (fuul or demo). What are your impressions?

Looks like a good tool for a small startup since they claim full integration.

Comments, reviews from the ID community please?

Thank you.
