Website Tech Stack Scraper

Find out what any website is built with, in bulk. Give it a list of domains and get back the technologies behind each one: CMS, ecommerce platform, analytics, ad pixels, JavaScript frameworks, CDN, hosting, payment providers, live chat, and more. A fast, reliable alternative to BuiltWith and Wappalyzer, with no account or API key required.

How it works

✨ Why teams choose this over other website technology scrapers

• 🎯 Real per-site detection, not stale directory data. Every result comes from analyzing the live website right now, so you see the stack as it is today, not a cached snapshot.
• 📚 Thousands of technologies, with versions. A library of 6,000+ fingerprints across every major category, and it reports version numbers when the site exposes them.
• 🌐 Beyond the page: email, DNS and SSL. It also reads DNS records to reveal the email provider (Google Workspace, Microsoft 365), the DNS provider, and the SaaS a company uses (from domain-verification records), plus the SSL certificate authority, signals a page scrape alone can never see.
• ⚡ Built for bulk. Feed it thousands of domains and it works through them in parallel, returning a tidy row per site.
• 🧩 Rich categories out of the box. Technologies are grouped into meaningful buckets like Ecommerce, Analytics, Advertising, CDN, Payment, and Live Chat, so you can filter and segment immediately.
• 🔓 No account, no API key, no credits elsewhere. Everything runs inside the actor. You only pay for the results you get.
• 💸 Priced to run at scale. Pay per result, with no monthly commitment.
• 🛠️ Clean, predictable output. One flat record per domain, ready for a spreadsheet, a CRM, or a data pipeline.

🚀 Examples

Audit a list of prospects

{ "startDomains": ["acme.com", "globex.com", "initech.com"], "maxItems": 500 }

Check a single site

{ "startDomains": ["example.com"], "maxItems": 1 }

💻 Integrations

Results are available as JSON, CSV, or Excel from the dataset, and through the Apify API. Connect the output to Google Sheets, Airtable, a CRM, or any data warehouse using Apify integrations and webhooks.

📈 Performance

The scraper analyzes many domains in parallel, so large lists complete quickly. A run of a few hundred domains typically finishes in a couple of minutes.

💡 Tips for best results

• Pass clean domains such as example.com. Full URLs work too, the host is extracted for you.
• Use maxItems to keep runs scoped and predictable when testing.
• Some technologies only appear on specific pages. The homepage is analyzed by default, which covers the vast majority of stacks.
• De-duplicate your input list to avoid paying for the same domain twice.

❓ FAQ

Which technologies can it detect? A library of 6,000+ fingerprints across CMS, ecommerce, analytics, monitoring, tag managers, advertising, JavaScript frameworks and libraries, UI frameworks, web servers, programming languages, hosting and CDN, bot management, payment providers, marketing and CRM tools, live chat, A/B testing, cookie consent, fonts, video, search, reviews, and accessibility.

Do I need a BuiltWith or Wappalyzer account? No. Everything runs inside the actor.

How fresh is the data? It reflects the website at the moment of the run, not a cached directory.

Do you detect email and DNS providers? Yes. The scraper reads MX, NS and TXT records to identify the email host, the DNS provider, the SSL certificate authority, and SaaS tools that publish domain-verification records.

What does confidence mean? A score from 0 to 100 indicating how strong the detection signal is. Matches from response headers and cookies score highest.
