Note that if you are currently using Falcon, another route to get many of these features is to use hug (https://github.com/timothycrosley/hug) which inspired many of API Star features back in the day - and is part of the Falcon ecosystem. But there's also a lot of really amazing work done in this ecosystem that hug doesn't currently support - I may have a busy couple of months ahead :).
