StackDetect
What it is
StackDetect identifies technologies used by websites and organizes them into searchable, exportable prospect lists. Detection covers CMS platforms, WordPress plugins, ecommerce applications, analytics tools, advertising pixels, JavaScript frameworks, CDNs, payment gateways, CRMs, and more. Lead records include a hostname, detected technologies and categories, confidence, HTTPS status, and last-seen date. Data is collected from publicly accessible pages through a browser extension and proprietary crawler; private or authenticated content is not accessed. The extension collects visited hostnames and detected technologies, not page content, form data, passwords, or personally identifiable information. Detection depends on public fingerprints and varies by technology, while less-visited sites may have data weeks old. The free plan costs nothing and includes 50 technology lookups monthly plus sample lead lists. Paid plans add bulk exports and advanced filters. Business and Enterprise add multi-technology filtering, CRM enrichment, and API keys; one technology lookup uses one credit.
