There are a number of add-on's for Fiddler, and every time I have to install Fiddler on a new machine I am always surprised when I go to use an inspector only to find out it is not there.

The best source of information for Fiddler Add-On's is the Fiddler Web Site itself. There is an Add-On link from the home page.

My favorites are:

The Syntax View Inspector

This add-on shows you syntax colored views of the captured session traffic.

The Web View Inspector

This inspector shows you the session data as it would be rendered via IE's rendering engine.

These are only two of the many available add-on's for Fiddler. But they give you a feel for what is available, and of course if there is a feature you want or need that is not already available, you can always write your own inspector!

Step by step instructions on building your own inspector are available here. Fiddler can be extended with .NET code or by using it's own built in Fiddler Script engine.
