Charles is an HTTP proxy / HTTP monitor / Reverse Proxy that enables a developer to view all of the HTTP and SSL / HTTPS traffic between their machine and the Internet.
This includes requests, responses and the HTTP headers (which contain the cookies and caching information).
In Web and Internet development you are unable to see what is being sent and received between your web browser / client and the server.
Without this visibility it is difficult and time-consuming to determine exactly where the fault is. Charles makes it easy to see what is happening, so you can quickly diagnose and fix problems.
Charles makes debugging quick, reliable and advanced; saving you time and frustration!
