Security reconnaissance

Identify externally visible web technologies, version clues, and related infrastructure signals during reconnaissance.

Wappalyzer helps security teams and researchers profile websites quickly, inspect stacks across multiple domains, and surface clues about CMS, frameworks, analytics tools, hosting, and other software that may shape follow-up testing.

Use it when you need externally visible technology fingerprints rather than vulnerability findings. Wappalyzer can return detected software, version clues when public signals expose them, and repeatable lookups across single sites or broader domain sets.
