Looks like a nice tool. I wrote https://github.com/epantry/django-sql-explorer, which is sort-of similar in terms of the problem it solves, except embraces SQL front-and-center. Excited to check this out in more depth.

Personally, I think it's really exciting is that this is all written in Clojure! We need more Clojure web apps out there to learn from! An initial glance at the source makes it seem very readable as well. A great learning resources for us amateur Clojurists. Also makes it clear that the ecosystem is pretty immature; there is a lot of frameworky boilerplate to support a straightforward REST API.
