It's hard to say. Delphix is quite opaque on what they do exactly and getting through requires booking a demo.

From what we have seen, Delphix is very much focused exclusively on large enterprise, and by extension does not look like a tool which is focused on the developer experience (could be wrong here).

We are much more focused at addressing the engineers in businesses - at the end of the day it's developers who will be using this tooling.
