Learn Fiddler with online courses and programs
What is Fiddler debugging tool?
When an internet user visits a website, they expect their browser to load the page without issue. One way that developers can test their code is through a web debugging proxy, which uncovers potential problems that could result in a loading error. By using Fiddler, they can perform various tests on the website’s actual performance and detect problems that can’t be seen without tracking network requests.
Fiddler is a web debugging tool that tracks network traffic between test computers and the internet. This provides programmers and other tech professionals with the power to inspect data and monitor requests before they hit the browser. It is compiled of five separate tools for debugging and troubleshooting code: FiddlerCore, FiddlerCap, Fiddler Jam, Fiddler Classic, and Fiddler Everywhere.Footnote 1
Fiddler runs on Windows, Linux, and macOS platforms, which makes it widely accessible by developers working today. Unlike other debugging tools included in major browsers, Fiddler software allows you to collaborate with others all over the world. It is also capable of handling complicated share, save, and customize requests, and offers dedicated email support.
