Charles Proxy
Charles Proxy is a cross-platform HTTP/HTTPS debugging proxy tool that allows developers to monitor, inspect, and manipulate network traffic between their computer and the internet. It acts as an intermediary server that captures all HTTP and SSL/HTTPS requests and responses, providing detailed information about headers, content, and timing. It is widely used for debugging web and mobile applications, API testing, and performance analysis.
Developers should use Charles Proxy when they need to debug network issues, analyze API calls, or test the behavior of web and mobile applications under different network conditions. It is particularly valuable for inspecting HTTPS traffic (with SSL proxying), simulating slow network speeds to test app performance, and modifying requests/responses on-the-fly for testing edge cases. Common use cases include debugging REST APIs, monitoring mobile app traffic, and security testing by examining data in transit.
