Websites Using Astro

The source-code fingerprint

astro-island Search all 324,374 results →

Astro hydrates interactive components as client islands, each rendered inside an <astro-island> custom element, so the astro-island tag appears on any Astro page that ships at least one interactive component.

Likely false positives: A floor by design: Astro's zero-JS default means fully static pages carry no <astro-island> and aren't counted; the broader /_astro/ asset path catches them but inflates the total with unverified trigram candidates.

Example websites using Astro

These domains all contain the astro-island 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 Astro we match the literal fingerprint astro-island, the code Astro 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.
