Runscope is a bit different in that it focuses more on API Testing, APItools focused on monitoring the live traffic to the APIs and controlling it with programmable middleware.
There's a bit overlap but it's definitely worth checking out both!
For clarity, we (I'm the CEO of Runscope) offer two products: Runscope Traffic Inspector for logging/monitoring traffic to any API and Runscope Radar for ongoing automated testing. I don't mean to hijack the thread, just want people to know we do a bit more than just testing. Congrats on the launch!
Yes. Also returning cached responses if you want. It is full blown programming language inside. Parse XML? Yes. Transform JSON? Yes :) Implement OAuth? If you dare :)
