This tool is a command-line utility designed for automated web resource discovery, fuzzing, and application structure mapping. It functions as a security-focused scanner that identifies hidden files, directories, parameters, and virtual hosts by injecting payloads into HTTP requests. By systematically testing how servers handle various inputs, it assists in mapping the architecture of web applications and uncovering potential security vulnerabilities.
The tool distinguishes itself through a highly concurrent engine that manages asynchronous request execution and recursive job orchestration. It allows for granular control over the fuzzing process, including pipeline-based payload mutation, dynamic input encoding, and the ability to integrate external tools for custom payload generation. Users can manage scan intensity through precise traffic rate controls and interactive execution adjustments, ensuring stability while navigating target defenses.
Beyond core discovery, the software provides extensive observability and reporting capabilities. It supports logic-based response filtering to isolate relevant findings from noise, audit logging for verifiable testing trails, and structured data export in formats like JSON and CSV. The tool also accommodates secure testing environments through support for client-side certificate authentication and persistent configuration management for standardized testing workflows.
