The source-code fingerprint

_paq Search all 941,477 results →

Every Matomo/Piwik install defines the _paq command queue (var _paq = ...; _paq.push([...])), so _paq appears inline wherever the tracker runs.

Likely false positives: None significant, _paq is a Matomo-specific global.

Example websites using Matomo

These domains all contain the _paq 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 Matomo we match the literal fingerprint _paq, the code Matomo 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.
