LightProxy

LightProxy is a cross‑platform web debugging proxy built on the Whistle framework and presents its controls through a Chrome DevTools‑style interface. It captures and displays HTTP/HTTPS traffic, allowing users to inspect request and response headers, bodies, and timing details in a familiar panel layout. The tool supports modifying and, responses on the fly, enabling developers to test changes without altering server code.

The application is targeted at developers and QA engineers who need to diagnose network issues, test API behavior, or debug client‑side interactions during web development. Its macOS‑centric core provides a stable environment for running the proxy locally, while the DevTools UI offers a visual workflow that aligns with common browser debugging practices.

What distinguishes LightProxy is its combination of Whistle’s programmable proxy capabilities with a graphical interface that mirrors Chrome’s developer tools, reducing the need to switch between command‑line configurations and browser panels. This integration streamlines the debugging process for users familiar with DevTools, while still exposing the full power of a configurable proxy backend.
