What you get
- Every technology detected, with its version and a confidence score
- What kind of technology each one is — CMS, analytics, CDN, payments, and so on
- Which signals gave it away: headers, cookies, scripts, JavaScript globals, the markup, DNS
How it works
- 1We open the URL in headless Chrome, so what the page loads with JavaScript is seen too.
- 2We read its markup, response headers, cookies, loaded scripts and JavaScript globals, and the site's DNS records.
- 3We match them against an open database of over 7,000 technology fingerprints.
What people use it for
- Qualify leads by the platform and tools their site runs on
- Audit what third-party scripts and trackers a site loads
- Spot outdated library versions worth checking for vulnerabilities
Frequently asked
Yes, it answers the same question: what a site runs on, from an open database of over 7,000 technology fingerprints, read off the page as a real browser renders it. The result is JSON you can use in your own code through the /technologies API.
Only what the page shows a visitor can be detected: a technology that only appears behind a login or after a click is not visible from one visit.
How sure the detection is, from 0 to 100. Most fingerprints are conclusive and score 100; weaker signals score less and add up when several are seen.
