How this works

SearchWebCode indexes the raw HTML, CSS and JavaScript source of public web pages. To find sites using Bootstrap we match the literal fingerprint bootstrap.min.css, the code Bootstrap 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.
