Defexity scans your live app from the outside and gives it a Production Readiness Score: security headers, exposed files, SEO, accessibility, performance and legal pages. Every issue comes with evidence and a ready-to-paste fix prompt for Cursor, Claude Code, Lovable, Bolt or Replit. Then it watches your app with uptime, API and real-browser checks, cron heartbeats and public status pages. The scan is free and needs no signup.
