Fiddler

Fiddler is a handy tool that helps you debug internet traffic for any app that uses a proxy. It automatically logs all the HTTP or HTTPS connections made on your computer, letting you analyze the data easily.

What’s Up with Fiddler for Mac?

If you're using a Mac, just a heads-up: Fiddler is currently in its Alpha stage and runs on the Mono framework. So, before installing Fiddler, make sure you've got that framework set up!

Supported Browsers

To record your traffic, Fiddler needs to work with a web browser. The good news? It plays nice with popular browsers like Mozilla Firefox, Google Chrome, Internet Explorer, Safari, and Opera.

Managing Web Sessions

You can use Fiddler to manage your web sessions and tweak requests or responses by setting breakpoints. Plus, it has a Composer panel where you can create specific requests. How cool is that?

Framework Compatibility

This utility doesn’t stop there! It works with different popular frameworks like .NET, Ruby, PHP, and Java. That means you can analyze traffic for various mobile devices and check if caches, headers, and cookies are transferring correctly.

Testing Security Levels

You can also use Fiddler to test how secure your websites or web applications are. It lets you decrypt traffic for certain sessions or even all of them at once. And don't forget—Fiddler shows you the size of pages so you can spot performance issues easily!

Add-ons and Extensions

If you're looking for more features, Fiddler lets you extend its capabilities by integrating small scripts or complex extensions. You can create your own add-ons or head over to the developer website to see if any of the “ready-made” extensions fit your needs.

In Conclusion

To wrap it all up: Fiddler is great for debugging internet traffic and spotting potential issues. Just remember that since it's still in Alpha stage, it might have some bugs here and there.
