From the maker
Stone estimates often confuse particle density with the bulk density of a delivered product. I built this tool so geometry, density, and overage remain separate and can be checked against a supplier quote.

Authority builder
This score tracks the signals that make a listing useful for discovery and trust. Payment is not part of the score, and the result does not guarantee ranking.
Visual proof
0/12Add a logo and a product screenshot so visitors and crawlers have richer product context.
Authority loop
The check looks for a public link between the configured product site and this listing. It does not verify ownership, endorsement, or search ranking. Payment does not change search-link treatment.

Good, with room to improve
You're on the right track. Address the warnings above - adding a Content-Security-Policy or enabling HSTS can push you to an A. Fix the issues and hit "Rescan" to update your grade.
AI makes it easy to build apps fast - but speed without security puts users at risk. We scan every listed app's HTTP headers to surface who's shipping responsibly. Security headers like HSTS, CSP, and X-Frame-Options are the baseline defenses every web app should have. A good score tells users: "this builder cares about my safety, not just shipping quickly."
