Fiddler is a tool for debugging web traffic. It's particularly helpful because you can customize it for specific needs using extensions and add-ons, and the tool provides a lot of useful information specific to web traffic. Fiddler Cap is a lightweight Windows-only version of Fiddler designed for non-technical users to capture web traffic and then share the data within the team for debugging. Fiddler Jam (Pilot) is a web-based troubleshooting solution for support teams looking to capture web traffic, web logs and web app screenshots without requiring any programming.
