Website Tech Stack Detector (Wappalyzer Alternative)

Find out what any website is built with — in bulk. Paste a list of domains and get each site's CMS, ecommerce platform, JavaScript frameworks, analytics and ad pixels, marketing & chat tools, payment providers, CDN, hosting and web server — plus, from public DNS records, the company's email provider (Google Workspace, Microsoft 365…), DNS host, email-sending services (SendGrid, HubSpot, Salesforce, Marketo…) and SaaS tools with verified domains (Atlassian, Zoom, Stripe, OpenAI, DocuSign…).

Fast HTTP-only analysis (no browser), $1.50 per 1,000 websites, no start fee, unreachable sites free.

Who is it for?

• Sales & lead gen — build lists of Shopify stores, HubSpot users, sites running Intercom, companies on Microsoft 365, etc., and personalize outreach
• Agencies & freelancers — qualify prospects (old WordPress, no analytics, no consent banner…)
• Competitive & market research — technology adoption across a list of domains
• Security & IT — inventory servers, CDNs, DMARC policy and third-party scripts

FAQ

How accurate is it? Detection uses response headers, cookies, meta tags, script URLs and HTML patterns on the page you give (usually the homepage). Tools loaded only after user interaction or only on inner pages may not be visible — pass a specific URL if needed.

Is it a Wappalyzer clone? No — it uses its own fingerprint set focused on the technologies sales and marketing teams care about, plus DNS-based detection Wappalyzer doesn't do.

Does it use a browser? No, which keeps it fast and cheap. Pure client-side-rendered sites are still detected through their scripts and headers.

Can I run it on 100,000 domains? Yes. Increase concurrency and set a "Max cost per run" if you want a hard cap.
