Test log (from our notes)

What works

  • Checker form submits to /site/<domain>/ with no login or captcha. villadoimperio.com fresh scan (/site/villadoimperio.com/?fresh=1
  • page stamp 'Scanned Oct 14, 2026'): AI BUILDER CHECK = 'Built with Base44'
  • tier Confirmed (the top tier
  • platform-served
  • not Strong evidence), 99% confidence, 2 signals: 'Base44 runtime authentication script' (fingerprint string base44_access_token) and 'App icon served from the Base44 per-app media store' (media.base44.com URL). Negative control example.com fresh scan: 'No AI builder evidence found', 33 fingerprints across 9 builders checked
  • no builder named
  • only Cloudflare CDN detected. Second Base44 site ironsighterp.info: fresh scan failed (see breaks)
  • its cached Oct 10 2026 report (viewed without new scan) shows Base44 Confirmed with the same two signal types. Base44 category page lists 2 indexed Base44 sites (villadoimperio.com
  • ironsighterp.info).

What breaks

  • 1) Fresh scan of ironsighterp.info (/site/ironsighterp.info/?fresh=1) returned 'Scan failed: A secure (TLS) connection could not be established with this website.' Not retried because of the 3-scan cap. Whether the cause is the target site or the checker is unverified. 2) Default form submit returns the cached report ('Cached Oct 14, 2026') rather than a new scan
  • fresh results need ?fresh=1 or Re-scan. 3) Fresh-scan reports omit the Re-scan button (confirmed again: page text shows Scanned, Copy, Export
  • with no Re-scan
  • cached reports show it). 4) No Strong evidence tier observed in any of the 3 scans today
  • the Base44 template signal (default page title) was not seen on either site.

Release claims checked

  • verified Detects 9 AI app builders (Lovable, Bolt.new, v0, Replit, Base44, Manus, Anything, Emergent, YouWare) (checker page builder table; example.com report text '33 fingerprints ... 9 AI app builders')
  • verified Names a builder only when its own fingerprint is found, and says so plainly when none (villadoimperio.com fresh report shows matched signals; example.com report says 'No AI builder evidence found')
  • verified Detects Base44 on villadoimperio.com source
  • verified Confirmed tier = served by the builder's own platform, so the owner cannot remove it (villadoimperio.com fresh report: Confirmed with platform-signal evidence; definition on checker page)
  • unverified Strong evidence tier = builder default tags left in generated source (checker page definition only; no Strong-tier result observed in 3 scans today)
  • unverified Base44 identified on 15 of 15 known test sites (Sep 17 2026 test run) (checker page accuracy table; only 2 Base44 sites spot-checked here)
  • unverified Accuracy 78/90 (87%), 0 wrong builder, 0 false positives across 109 controls (Sep 17, 2026) (checker page; not reproduced)
  • unverified Fingerprints re-run whenever a fingerprint changes (checker page accuracy section)
  • unverified Narrowed a Base44 rule after it flagged Base44's own marketing site (checker page accuracy section)
  • unverified Makes a single ordinary page request to the target site (checker page FAQ; no network capture done)
  • verified Free, no account needed (3 scans plus cached lookup with no login, paywall or signup prompt)
