Proxie

Proxie is a native macOS application that functions as an HTTP debugging proxy, allowing developers to capture and inspect network traffic generated by their applications. It supports HTTPS decryption through a man‑in‑the‑middle approach, exposing request and response details that would otherwise remain encrypted. The tool provides a comprehensive filtering system with quick search, URL hierarchy view, and customizable user filters to help locate specific requests among large volumes of data.

The proxy includes a rule engine that can manipulate traffic on the fly. Basic rules such as mapping local resources or disabling caching are configured through an intuitive interface, while more advanced behaviors can be scripted with JavaScript. These rules enable pausing, editing, and dynamically altering requests and responses during a debugging session.

Designed exclusively for macOS 10.13 or later, Proxie leverages native macOS technologies to deliver low RAM usage and minimal impact on battery life, offering a responsive and familiar user experience for developers who need detailed insight into HTTP and HTTPS communications.
