What it is

StackDetect detects and catalogs technologies used by websites, then lets users search, filter, and export prospect lists based on those technologies. It covers CMS platforms, WordPress plugins, ecommerce apps, analytics, advertising pixels, JavaScript frameworks, CDNs, payment gateways, CRMs, and more. Lead lists group websites by the tools they use for outreach, enrichment, or analysis. Each record includes a hostname, detected technologies and categories, confidence, HTTPS status, and last-seen date. Data comes from public 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; less-visited sites may have data weeks old. The free plan costs nothing and includes 50 technology lookups per month and sample lead lists. Paid plans include bulk exports and advanced filters; Business and Enterprise add CRM enrichment and API keys. Each API lookup uses one credit. Included API credits expire after 60 days; purchased top-ups do not.
