FAQ
Frequently asked questions
What is a website tech stack detector?
A tool that scans any URL and identifies all the technologies it uses — CMS (WordPress, Shopify), frontend frameworks (React, Next.js), analytics (GA4, Hotjar), CDN (Cloudflare), hosting, and more. It analyzes HTTP headers, JavaScript libraries, HTML meta tags, and network requests.
How many technologies can it detect?
Over 6,000 web technologies across 31+ categories — CMS, ecommerce, analytics, advertising, A/B testing, CDN, hosting, email marketing, JavaScript frameworks, and server-side technologies.
Is it free to use?
Yes. Apify offers a free tier for scanning websites. For bulk scanning (hundreds or thousands of URLs), you pay per usage — around $0.003 per website scanned.
How is this different from BuiltWith or Wappalyzer?
Apify detectors run in the cloud — scan thousands of URLs in bulk via API. Unlike BuiltWith, pricing is pay-per-use (no $295/mo subscription), and you get full API access with webhooks and scheduling.
Can I use it for lead generation?
Absolutely. Scan competitor customer sites to find which ones use specific tools (HubSpot, Salesforce, Shopify), then target those companies. It's one of the most powerful B2B lead gen strategies.
