Hi there, I'm Jean, the founder and CEO of Akita. Thanks for the great question! We designed our tool very much in the spirit of tools like Pact, but to support much more automation. Pact is great if you 1) know your API and 2) know the contracts you want to test your API against.
Akita is able to:
* Automatically infer your API and automatically generate a spec
* Automatically infer properties of your API that it observes (implicit API contracts), so you can diff/test against those later
* (Coming soon) Automatically generate tests for your API against those contracts
