Fiddler 220.127.116.11 Alpha
A simple Mac OS X application that works on the Mono platform and allows you to debug your internet traffic for any app that can use proxies.
Note that the Fiddler for Mac is currently in Alpha stage and uses the Mono framework to run. To be able to install the Fiddler app you must make sure the framework is installed beforehand.
At the same time, Fiddler needs to use a web browser to record your traffic. However, the application is able to work with most popular browsers, such as Mozilla Firefox, Google Chrome, Internet Explorer, Safari or Opera.
Fiddler can be used to manage your web sessions and alter the request or response by setting up a breakpoint. What’s more, the app allows you to create specific requests via the Composer panel.
The utility is also able to work with different popular frameworks, such as NET, Ruby, PHP or Java. As a result, you will be able to analyze the traffic for different mobile devices and verify if the caches, headers and cookies are transferred properly.
Moreover, you can use Fiddler to test the security level of your websites or web applications. You will be able to decrypt the traffic for a certain session or for all of them. Last but not least, Fiddler offers you the possibility to view the size of a page and helps you identify performance issues.
Noteworthy is that the Fiddler capabilities can be extended by integrating small scripts or more complex extensions. You can create your own add-ons or you can navigate to the developer website and check if any of the “ready-made” extensions suits your needs.
To sum up, Fiddler can be used to debug the internet traffic and identify possible issues but keep in mind that the application is in Alpha stage and comes with many bugs.
