My book “Debugging with Fiddler”, is now available

I’m delighted to announce that my new full-length book on Fiddler is now available. Weighing in at 330 pages, it covers every feature in Fiddler, and provides the most comprehensive available documentation of how to develop Fiddler extensions (including Inspectors, Transcoders, and IFiddlerExtensions) and build on the FiddlerCore class library. The book is available in paperback and DRM-free PDF formats.

You can learn more about the book at The site includes a link to the final Table-of-Contents, as well as all of the code samples in the book.


Thanks for your interest in Fiddler!

    I am new to fiddler world, but it seems quite interesting to me that we can debug our HTTP / HTTPS calls flawlessly.

    Can you suggest me how to go around, also is this book useful for starters.

    @Om: I'm not sure what "how to go around" means, but yes, this book is great for beginners.
