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.
Find better prospects from the technologies they use
See the technologies behind any company website so you can qualify leads faster, personalize outreach, and enrich your CRM with technology, company, and contact data.
Map website-serving subdomains for technical discovery
Discover active website-serving subdomains for a domain so you can map exposed web assets, uncover product, support, and regional properties, and feed internal inventory or security workflows with cached discovery data.
Automate website intelligence and enrichment workflows
Use Wappalyzer APIs to qualify accounts, build lead lists, enrich CRM records, discover subdomains, and verify email addresses. Combine fast cached results with live analysis when you need up-to-date website and company intelligence in your own product or workflow.
Track technology changes on important websites
Monitor competitor, prospect, and customer websites for technology changes. Spot migrations, new tools, and timing signals early so your team can act faster.
Bring website intelligence into the tools your team already uses.
