Astro Showcase CMS Detector

Detection is automated: each site is fetched and inspected for Astro fingerprints (script filenames, meta generators, HTTP headers) and CMS signals (API endpoints, script patterns, DNS records). It's accurate but not infallible.

Caveats: some sites block scrapers, redirect away from their Astro front-end, or don't expose version signals. Sites marked "Astro not detected" may have migrated to another platform, may be behind a CDN that strips headers, or simply couldn't be reached at scan time. Confidence badges (high / medium / low) reflect how many signals were found.
