The source-code fingerprint

fbevents.js Search all 3,013,903 results →

The pixel library fbevents.js is loaded from connect.facebook.net and initialized with fbq('init', <id>).

Likely false positives: Matching the library specifically (not just connect.facebook.net) keeps this to real Pixel installs, not other Facebook widgets.

These domains all contain the fbevents.js 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 Facebook Pixel we match the literal fingerprint fbevents.js, the code Facebook Pixel 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.
