Can you explain what this means?

This acts as a proxy server for any API. All the request capture by intercept and it'll capture the response from the original endpoint and reply back

This is the same for HTTPS traffic? You can view the content of requests without installing a cert?

Yup, this works both HTTP and HTTPS without any certs.

Hope this helps

Thanks!

I would really appreciate if you could give us some honest feedback. or any suggestion

Thanks

I've used mitmproxy in the past for debugging purposes but there was always a stipulation that one must install a cert on the machine in order to intercept HTTPS traffic. If intercept.rest can accomplish the same thing without the need to install a cert I could see this being very useful.

Yes, this can work without certificate installation and you don't have to do anything in client side. Only need to change the endpoint URL
