The source-code fingerprint

challenges.cloudflare.com/turnstile Search all 205,360 results →

The widget API loads from challenges.cloudflare.com/turnstile/v0/api.js and renders into an element with the cf-turnstile class.

Likely false positives: None significant; the challenges.cloudflare.com/turnstile path is specific to Turnstile and distinct from Cloudflare's other products.

Example websites using Cloudflare Turnstile

These domains all contain the challenges.cloudflare.com/turnstile fingerprint in their homepage source right now. A match is a verified substring of the live page, so confidence is high, the false positives noted above are the main caveat.

How this works

SearchWebCode indexes the raw HTML, CSS and JavaScript source of public web pages. To find sites using Cloudflare Turnstile we match the literal fingerprint challenges.cloudflare.com/turnstile, the code Cloudflare Turnstile ships, against that index, then verify each match against the raw source. Counts reflect the current index (129,313,463 domains, refreshed monthly, last built August 2026) and grow as we scale toward the whole web. Run the search yourself to see every match, view the full page source for any result, filter by TLD or regex, and export the domain list.
