Charles is a proxy server and tool for monitoring and analyzing HTTP/HTTPS traffic between a client and a server. It is actively used by QA engineers to debug applications, test API functionality, and analyze network requests. Charles allows you to record, replay, and even modify requests and responses, which greatly simplifies the process of identifying and fixing bugs in applications.

With Charles, you can perform security and performance testing, as well as simulate various network conditions, such as delays and failures. This makes it indispensable for testing applications in real-world conditions, identifying bottlenecks, and analyzing performance issues.

For businesses, Charles helps reduce the risks associated with faulty integrations and APIs and cuts down on debugging and testing time. This contributes to improved product quality, fewer critical defects, and increased user satisfaction
