The best thing about this tool would be that I can use it in any language with ease of understanding even if its not my main programming skillethen i can still implement everything easily without having to go through so much documentation. Its hard initially using their tutorials but once you get used to them then they are very helpful. Also the support team really help when there is something stuck or some issue arises during implementation. If your looking into developing an api integration between server side applications than surely try out mocking tools like MOCKLETS! We have been able to integrate our backend services easier by implementing apis developed in other languages such as node js etc.
