How does Tyk differentiate from Kong(http://getkong.org/)?
Tyk Cloud was very much built to make the open source and free versions better (and sustainable), so I think there's probably some differences in motivation.
Ultimately we're trying to solve the same problems, which is great, we're seeing more and more projects try to make API management better, just noticed the other day that a new ruby-based app has shown up called API Umbrella (http://apiumbrella.io/)! It's getting busier, which is great news for API developers.
