This is awesome.. And Immediately runs into the problem of being purely SaaS. I can't use this for APIs that I develop internally within my 'Big Company'.

If I could host this somewhere behind my firewall, then something like this becomes a no brainer. But making me try to convince my security team to send all of my API calls and design to an external service puts a huge barrier to entry for me politically.

I love the idea to the point that I started searching for something similar that I could host inside. Even Github lets me host a copy of their software somewhere nice and corporate safe.

I wish more service providers would offer more than just 'pure SaaS' to allow for easier adoption by corporate customers.
