Fiddler

A widely used HTTP debugging proxy tool for the Windows platform that captures and analyzes network requests from web and mobile applications. It enables developers and testers to inspect, modify, and replay HTTP/HTTPS traffic, making it a standard utility in software testing and API debugging workflows.

Decrypting HTTPS traffic in Fiddler requires installing its root certificate on the device; the underlying principle is replacing the server certificate with a self-signed certificate to complete a decrypt-inspect-re-encrypt workflow.

Verified

Charles and Fiddler are essentially HTTP/HTTPS proxy servers that intercept traffic via a man-in-the-middle approach, requiring a self-signed CA certificate to be installed on the device for HTTPS traffic.
