Hey, This is Sachin - founder @ Requestly. At Requestly, We have solved primarily the problems of web developers often needing the capabilities to test local scripts in production (or staging environment), modifying headers, host scripts online. Even today, tools like Charles, Fiddler fail to solve simple use cases of Redirection, Headers, Simulating Delays, Scripts Injection in a simple user-friendly way. After all, developer experience also matters :-) Also, Setting up the desktop app vs the browser extension, the difference is way huge. It's way easier to work with browser extension when it comes to your intercept & modify browser traffic. As of Now, We have started to get requests to scale Requestly to other platforms to debug Mobile & Desktop app traffic too hence we have recently started to work on the desktop app (https://requestly.io/desktop https://requestly.io/desktop) (It's still in beta but usable). Here's a video a friend created sometime back - https://www.youtube.com/watch?v=LUqlA9j9Lx4&t=1s https://www.youtube.com/watch?v=LUqlA9j9Lx4&t=1s which explains how you can modify headers using Requestly desktop app. We'll try our best to solve the problems with Requestly that still exists in Charles, Fiddler and similar tools.
