What it does

This is a website technology lookup you can run on a list. It fetches each homepage and matches public fingerprints, in the same spirit as tools like Wappalyzer. You get a full technologies list, plus fields for cms, ecommerce, analytics, cdn, server and frameworks.

It skips private URLs, robots.txt blocks, unreachable sites, non-HTML responses, login walls and bot-challenge pages, and it does not charge for those. No browser is involved, so technologies that only appear after JavaScript runs may be missed.

Who it is for

It is useful when you have a list of sites and need a quick, honest read on what they run.

  • Lead generation and sales research on a list of company websites.
  • Competitive research when you want CMS, analytics and CDN at a glance.
  • Agencies asking 'what is this client's site built on' before a call.

Price

$0.50 per 1,000 analyzed sites ($0.0005 per site). That is the live Apify Store price as of November 11, 2026. Failures are free.

A 2,000-site lead list costs at most $1.00. You can cap the number of sites or the maximum charge on the run.

Example input and output

Input

A short list is enough for a trial. A domain without https:// is fine.

{
  "urls": [
    "wordpress.org",
    "https://www.allbirds.com/"
  ]
}

Output

A shortened row. The full run also includes the technologies list and other group fields.

{
  "input": "wordpress.org",
  "url": "https://wordpress.org/",
  "cms": "WordPress",
  "server": "Nginx",
  "technologyCount": 12,
  "status": "ok"
}
