Charles is a powerful and comprehensive web proxy designed to run on your Mac in order to help you keep a close eye on all the traffic going in and out of your computer.

Makes it possible to monitor the traffic of any application on your Mac that connects to the Internet

Once Charles is up and running on your Mac, the default web browser (or, for that matter, any other Internet enabled app) can be configured to go online via Charles' built-in proxy.

After the monitored app connects the Internet through Charles, it will then start to record all the traffic and the data sent and received by the application to and from the Internet.

Moreover, Charles makes it very simple to find out why your application has a difficult time reaching an online device and to quickly find out what is the bug in your code that's causing it.

In conclusion, Charles' main goal is to provide you with all the tools needed to effortlessly pinpoint and fix all Internet connection related problems and bugs in your app.

Provides a robust built-in W3C code validation tool and the possibility to use breakpoints while monitoring an app’s traffic

Additionally, besides being able to capture web traffic, Charles also comes with the capability to help you add various types of breakpoints, all designed to ease the interception and editing processes for responses and requests.

Furthermore, Charles also allows you to swiftly validate any recorded HTML, RSS/Atom or CSS code responses with the help of W3C's code validator.

Even more, the Charles utility will also make it very easy and fast to edit and repeat any number of requests in order to test a diverse assortment of back-end changes and inputs.
