Wappalyzer-Next is a command-line tool and Python library that detects technologies using the Wappalyzer extension and its fingerprints. It bypasses limitations of other projects that emerged after the official open-source project was discontinued. To install Wappalyzer, you need to install Firefox and geckodriver. Geckodriver can be downloaded from the official GitHub releases page and added to the system path. Wappalyzer can be installed as a command-line tool using pipx or as a library using pip. It can also be installed and run using Docker Compose. The tool can be used to scan single or multiple URLs, with options for authentication, output formats, and scan types. The Python library is available on PyPI and can be imported as wappalyzer, with a main function called analyze(). The analyze function takes parameters such as URL, scan type, threads, and cookie, and returns a dictionary with detected technologies. The scan types include 'fast', 'balanced', and 'full', which differ in the level of HTTP requests and browser emulation used.
