mitmproxy is - as the name suggests - a proxy.
At Requesty, I do a lot of request manipulation, from one format to another. We listen to a lot of streams. Basically we do a lot of networking.
So, when I need to understand the shape of my outgoing requests, where logging or debugging might be enough, I reach for mitmproxy.
You start it by:
mitmproxy --mode reverse:https://google.com
I use it in reverse mode almost exclusively. This is because I mostly want to debug outbound requests.
Then all you have to do is make a request!
mitmproxy will show you all your outbound requests, the response, the headers and a lot more options (you can even replay requests!).
If you do any kind of requests and have ever had to debug them, I highly recommend you give this tool a try.
