Website Technology Detector – CMS, Tech Stack & Outdated Software

Find out what any website is built with. Paste a list of domains and get, for each one, the CMS or site builder, e-commerce platform, JavaScript frameworks, analytics and ad pixels, cookie consent tool, live chat, booking widget, hosting / CDN and web server, with versions when they are exposed and a clear outdated software flag.

It is a lightweight Wappalyzer / BuiltWith alternative that runs in bulk on Apify: no browser, about one second per website, and you only pay for websites that were actually analyzed.

Outdated software flags

Each technology gets outdated: true with a plain-English reason when the detected version is end of life or known to be vulnerable, for example:

• WordPress below 6.4, PHP below 8.1, jQuery below 3.5, Bootstrap 3 or 4
• Drupal 7/9, Joomla 3/4, AngularJS, Flash
• Universal Analytics still installed (it stopped collecting data in July 2023)

This makes the Actor useful for lead generation (sites that need a rebuild), security reviews and competitor research.

How to use it

1. Add domains or URLs to Websites (example.com or https://example.com).
2. Or chain it after another Actor: put that run's dataset ID in Read URLs from a dataset and the field name (default website), for example the output of a Google Maps scraper.
3. Click Start. Results appear in the Overview table and the Outdated software only view, and can be exported to CSV, Excel or JSON.

Input example

{
  "urls": ["wordpress.org", "shopify.com", "example.com"],
  "maxConcurrency": 10
}

Output example

{
  "url": "https://example-bakery.com/",
  "domain": "example-bakery.com",

  "technologyCount": 7,
  "technologies": [
    { "name": "WordPress", "category": "CMS", "version": "5.2.4", "confidence": "high", "evidence": ["meta generator", "html"], "outdated": true, "outdatedReason": "WordPress below 6.4 ..." }
  ]
}

A SUMMARY record in the key-value store gives totals per CMS and the number of sites with outdated software.

Pricing

Pay per event: $3 per 1,000 websites analyzed. Websites that cannot be reached (DNS error, timeout, HTTP error) are listed in the results but not charged.

Good to know

• Only the homepage is fetched, with one plain HTTP request. Technologies that only load after JavaScript runs, or only on inner pages, may be missed.
• Versions are shown only when the website exposes them.
• Detection is done from public HTML and HTTP headers. No login, no personal data.
• Use Apify Proxy (in Advanced) if many websites in your list block data-center traffic.
