webanalyze is a high-performance Go port of Wappalyzer designed for automated mass scanning to identify web technologies used on websites.
Port of Wappalyzer (uncovers technologies used on websites) to automate mass scanning.
This tool is primarily used by security professionals, web analysts, and penetration testers to quickly identify technologies deployed on large lists of websites, aiding in vulnerability assessment and security automation. It is ideal for scanning multiple hosts efficiently and integrating technology detection into automated workflows.
Because Wappalyzer removed public access to their app definitions, webanalyze relies on an alternative open-source definitions source; users should regularly update the technologies.json file using the -update flag to maintain accuracy. The tool is optimized for performance and mass scanning but requires familiarity with command-line usage and optionally Docker for containerized deployment.
