I work on a GraphQL-based e-commerce framework and several of my users have had good experiences integrating GraphCDN/Stellate into their projects.
Recently I started working with it too and so far the product has been great to work with. Moreover their team is very responsive. I had a technical question regarding my integration and one I was able to schedule a call for the next day with one of their team and to my surprise he'd prepared a script to solve the exact issue I was asking about (thanks Jovi)!
Congrats to the team!
