This web traffic debugging tool, inspired by Charles, uses an HTTP/HTTPS proxy to analyze and intercept requests directly from your browser on Windows. It lets you view all requests and responses in real-time, find errors, inspect form data, and analyze interactions with external services. A key feature is URL mapping for automatically redirecting requests based on patterns to local paths, perfect for testing different versions in a development environment. It supports encrypted HTTPS traffic for secure analysis of protected requests, such as in applications with payments. This is an open-source application; however, active development ceased in 2019, and HTTP Toolkit is recommended for modern browsers.
