React security check

Scan your React app for security gaps

Seven automated checks for React apps: exposed secrets, Supabase misconfiguration, auth flow, payment path, broken links, and performance.

React apps move secrets to the client when developers (or AI tools) forget that client components run in the browser. This scanner checks your live React app for the seven most impactful issues: SSL/reachability, auth flow, payment paths, client bundle secrets, Supabase exposure, broken links, and initial response performance.
