About:
Katana is a fast and flexible web crawling framework designed to discover endpoints and assets within web applications. It operates as both a standalone crawler and a library, enabling developers to build custom crawling logic. The tool excels at processing complex JavaScript-heavy sites to map out attack surfaces for security assessments.
Key Features:
  • Headless browser support for modern web applications
  • Flexible output formats (JSON, CSV, etc.) for integration
  • Configurable crawling depth and scope
  • Automatic handling of authentication and session management
  • Extensible via Go modules for custom functionality
Use Cases:
  • Reconnaissance and mapping of web application attack surfaces
  • Automated asset discovery for penetration testing engagements
  • Extracting endpoints for API security analysis
  • Building custom web scrapers for data collection
Alternatives:
  • gau – Fetches known URLs from AlienVault's OpenThreat Exchange, while Katana actively crawls live targets
  • waybackurls – Retrieves historical URLs from Wayback Machine, whereas Katana discovers current active endpoints
  • hakrawler – Lightweight Go crawler focused on simplicity, Katana offers more advanced features and JavaScript rendering
