Tech Stack Detector 🔍

Find out what any website is built with — and how to reach the people behind it.

Give it a list of websites and get back each one's complete technology stack (CMS, ecommerce, frameworks, analytics, CDN, server, JavaScript libraries, payment and marketing tools) with categories and versions — plus the technographic and contact signals most detectors skip: email provider, SSL issuer, hosting, emails and social profiles.

A BuiltWith & Wappalyzer alternative that turns technology detection into ready-to-use sales leads — no code required.

📌 Why this Actor?

Most tech detectors stop at a list of technologies. This one is built for technographic lead generation — it adds the signals sales, marketing and research teams actually act on:

• 🧩 Complete stack — hundreds of detectable technologies across CMS, ecommerce, frameworks, analytics, tag managers, CDNs, web servers, programming languages, payment processors and marketing tools.
• 📧 Email provider — is the company on Google Workspace or Microsoft 365? Detected from the domain's DNS MX records — a powerful qualification signal.
• 🔒 Infrastructure — SSL certificate issuer & expiry, CDN, web server and IP address.
• 📇 Contact data — emails, phone numbers and social-media profiles pulled straight from the site.
• 📦 Built for bulk — feed a list of prospect domains and get an enriched technographic dataset back.

The result: not just what a site runs, but who to contact and how they're set up.

💡 Tips & best practices

• ✅ Feed clean domains — example.com or a full URL both work; https:// is added automatically.
• ✅ Qualify by email provider — Microsoft 365 vs Google Workspace is a strong segmentation signal.
• ✅ Group by category — use technologiesByCategory to filter for a specific stack (e.g. all sites with Klaviyo).
• ✅ Turn off enrichment you don't need (SSL / contacts) to run even faster.
• ✅ Scale up — raise concurrency and load domains from a file for large lists.
• ✅ Combine signals — tech + email provider + contacts = a complete technographic lead.

❓ FAQ

What technologies can it detect? Hundreds — across CMS, ecommerce, JavaScript frameworks, analytics, tag managers, CDNs, web servers, programming languages, payment processors and marketing tools, with categories and versions where available.

How is this different from a plain tech detector? It adds the technographic lead layer: email provider (DNS MX), SSL issuer, hosting/IP, and on-page emails, phones and socials — so each result is a usable lead, not just a tech list.

Do I need to code? No. Paste your domains, click Start, and export.

Can I analyse thousands of websites? Yes — load them from a file or URL list and raise concurrency.

Why do some sites show few technologies? Highly custom or heavily protected sites expose fewer fingerprints. Infrastructure and DNS signals (email provider, SSL, IP) are still returned.

In what format is the data? Structured JSON by default, exportable to CSV, Excel, HTML or via API.
