Requestly

This is an unbelievably useful system that has already saved me an enormous amount of time. I happily signed up for 10 codes so that I could get the HTTP Rules Access (Professional Plan).
My review directed at that aspect of the product: For this part alone it's worth the price of admission. I am now able to create responses to my api calls so that I can proceed with working on my front end without having to wait for the backend developer. I didn't understand the setup initially but was quickly helped via email and chat and was able to get the setup working within minutes. I believe someone more familiar with APIs would probably have had an easier time (I am new to Vue and front end work). Imagine Postman except it's much easier to setup, works in both directions, and has an exhaustive list of extra tools for configuring every aspect of traffic.
My thoughts on the main product:
The main product was used to effectively troubleshoot the secondary product to get it working! It is phenomenal. It encapsulates every aspect of an operation and you are able to create a link to send to someone who can review your actions on a video while looking at all the traffic taking place while these actions are being done. There is even a desktop application for it, as well as a browser tool that with one click will intercept using your rules.

I am very, very happy with my purchase. Keep up the great work!!!! 🙂
