Charles is an HTTP proxy, HTTP traffic monitor, and reverse proxy that allows a developer to view all HTTP and SSL/HTTPS traffic between their computer and the Internet.
This includes requests, responses, and HTTP headers (which contain cookies and caching information).
When developing web content and working with the Internet, it is usually impossible to see what data is being transferred between your browser (client) and the server.
Without this visibility, it can be difficult and time-consuming to determine where exactly an error is occurring. Charles makes it easy to analyze what’s going on, allowing you to quickly diagnose and fix problems.
With Charles, debugging is fast, reliable, and advanced, saving you time and hassle!
