I like that they offer free tier for small projects which gives me confidence in their platform without spending money upfront when i have no idea what this tool will do or how well its going be used as an integration of my products into each other - nothing so far but very promising! It needs more documentation/tutorials about best practices etc..
And also there are few bugs here nthere after you start your implementation if not handled properly by team can make things harder than expected while learning new tools at least give tutorials first before asking question online community would help us solving issues faster :) we use xrty within our own organisation internally where all members work together closely related areas eCommerce site web application backend services monitoring infrastructure automation configuration management CI CD Continuous delivery Data analytics data science.
