I can't help but notice that this looks more like an enterprise integration tool (think mulesoft) than API management (think apogee.. or I think that is what they do).

Speaking somewhat from experience (webmethods, caml, spring-integration and various other enterprise integration tools) they always want you to use "their" DSL which is often not even stored on the developers filesystem (ie webmethods... you submit the code to the "broker" or "rules engine" or "router"... lots of words for thing that does the work). Which leads to very awkward development.

Consequently I wonder if they will have git integration because writing code even snippets in a web form no matter how nice gets old fast.
