Charles is an HTTP proxy, HTTP traffic monitoring tool, and reverse proxy server that helps developers view all HTTP and SSL/HTTPS traffic transmitted between their computer and the internet.

This data includes requests, responses, and HTTP headers, which also contain information related to cookies and caching.

When doing web development and internet-related work, it is often difficult to see directly what data is actually transmitted between the browser (client) and the server.

Without this information, pinpointing where errors occur is often both difficult and time-consuming. Charles makes the entire communication process more visible, helping you quickly analyze, diagnose, and fix issues.

With Charles, the debugging process can become faster, more reliable, and more efficient, saving a significant amount of time and reducing unnecessary complexity.
