Likely false positives: Sites that serve Fastly via a custom (CNAME'd) domain won't expose a fastly hostname in HTML.

Example websites using Fastly

These domains all contain the .fastly. 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 Fastly we match the literal fingerprint .fastly. — the code Fastly ships — against that index, then verify each match against the raw source. Counts reflect the current index (97,179,967 domains, refreshed monthly, last built July 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.
