Security Headers Report
Scanned 31 Mar 2026, 11:07
Action needed
Your app is missing critical security headers that protect users from XSS, clickjacking, and data leaks. Review the failing checks above, add the recommended headers to your server config, then click "Rescan". A stronger score helps you rank on the Security Leaderboard.
Why Security Scores Matter
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."
