WebTech is a Python-based tool for detecting technologies used on websites. It analyzes HTTP responses by examining headers, HTML content, meta tags, cookies, JavaScript, and URL patterns to identify web servers, frameworks, CMS, and other technologies. The tool provides both a command-line interface and a library API, with optional integration as a Burp Suite extension for active/passive scanning. Technology detection relies on a JSON-based signature database that is regularly updated from a Wappalyzer-compatible source. The architecture is modular, separating concerns into distinct modules: database management (downloading and merging signature files), HTML parsing (extracting meta tags and scripts), core detection logic (checking each technology signature across multiple vectors), and utility functions. The command-line tool processes single URLs or files containing multiple URLs, outputting results in human-readable, grep-friendly, or JSON formats. The Burp extension functions as a passive scanner, analyzing traffic intercepted by Burp Suite. While the core detection logic is well-structured and demonstrates reusable patterns, the codebase shows signs of technical debt. It maintains Python 2/3 compatibility (increasing burden as Python 2 is EOL), disables SSL verification by default (creating security risks), and the Burp extension depends on outdated Jython 2.7.0. The dependency on an external signature database introduces potential fragility if the upstream format changes. Despite these issues, the modular design allows for extraction of reusable components such as the Tech namedtuple, custom JSON encoder for sets, and HTML parser for meta/script extraction.
