Icon of Fiddler Classic

Fiddler Classic is a powerful web debugging tool that logs all HTTP(s) traffic between a server and its client in order to provide a complete picture of how different responses work. It allows you to analyze and examine HTTP and HTTPS traffic from browsers and desktop applications. It allows you to see all communication at a glance, or to dig deeper and see more.

By monitoring all the HTTP requests and responses, you can quickly identify communication errors in your application’s infrastructure. It produces detailed coverage of an HTTP request, including its headers, body, cookies, and attachments. With Fiddler, you can analyze how web pages are performing and define security policies, as well as improve developer productivity.
