AI builder check
No AI builder evidence found
None of the 33 fingerprints we track for 9 AI app builders (Lovable, Bolt.new, v0, Replit, Base44, Manus, Anything, Emergent and YouWare) appear on this page. That is not proof the site was coded by hand: code written with AI assistants such as Cursor, Claude Code or GitHub Copilot leaves no public trace, and builder markers can be removed after an export.
This check names the builder platform from public evidence. It does not measure how much of the code was written by AI. How the check works and how accurate it is
