    Fiddler is for super-user, and unfriendly for newbie. Proxyman is designed by strictly following the macOS human guideline from Apple, so it feels like the home.

    It is free, based on a open-source base implementation and is able to analyse not only HTTP/v1.1, but also HTTP/2 and HTTPS traffic. It is easy to configure and under Windows integrates itself as system proxy, so that the client programs do not need to be reconfigured.
