Hi Product Hunt, I'm the maker of Defexity.
I kept shipping apps built with AI tools and finding out about broken things from users: a missing security header, an exposed file, a form that failed on mobile. So I built a scanner that checks your live app from the outside, gives it a score from 0 to 100, and writes a fix prompt you paste straight into Cursor, Claude Code, Lovable, Bolt or Replit.
The scan is free and needs no signup. After you ship, Defexity keeps watching with uptime checks, API checks, real-browser flows, cron heartbeats and a public status page.
It cannot see inside your code, so it will not catch logic bugs; a code scan covers some of that.
What would you want it to check that it does not today? I read every reply and ship fixes fast.
