Debugger

This project is a browser developer tool designed for inspecting JavaScript execution, network traffic, and page layouts. It functions as a JavaScript debugger and a Chrome DevTools Protocol debugger to manage the state of a web engine and identify logic errors in web applications.

The suite provides specialized utilities for web performance profiling, including the detection of memory leaks and the analysis of processing bottlenecks. It also includes a network traffic analyzer for troubleshooting API calls and a browser storage manager for modifying cookies, cache, and local database entries.

Additional capabilities cover web page layout analysis, mobile device emulation to verify responsive displays, and the monitoring of application logs. The toolset supports source map resolution to link compiled code back to original files and allows for the connection of external editors.

    Firefox is a cross-platform web browser engine designed to render web content, execute JavaScript, and manage secure browsing sessions. It utilizes a multi-process isolation architecture that distributes browser tasks across independent operating system processes to ensure stability and prevent site-specific failures from impacting the entire application. The engine incorporates a sandboxed execution environment to restrict web content and untrusted scripts to isolated memory compartments, enforcing security policies that prevent unauthorized access to system resources. The project distinguis

    GodEye is a runtime instrumentation tool and observability framework for Swift mobile applications. It functions as a mobile application debugger and in-process diagnostic overlay, providing a visual interface rendered directly over active applications to monitor metrics and inspect system states without requiring changes to the original source code. The framework enables real-time analysis through a suite of debugging workflows. It captures diagnostic data using method swizzling and system-level hooking to intercept function calls and monitor internal application behavior. The tool covers s
