Milo's Launch Check looks at your live app the way a stranger would. Built for people shipping with Lovable, Bolt, Cursor, Replit or v0, it checks for exposed secret keys, open database tables, exposed files like /.env and missing security headers. Every finding comes with a copy-paste prompt you give to your AI coder to fix it. Checks are passive and read-only, only for apps you own. Start with the free 10-second header check, no signup. Not a penetration test.
