Afterprompt is a security scanner for apps built with AI coding tools like Lovable, Bolt, Cursor, v0 and Replit. Paste your URL and the free scan checks what anyone can see from outside: secret keys in your JavaScript, exposed .env or backup files, open Supabase tables and missing security headers. You get a grade from A to F and a plain-English fix for each problem. Paid plans also scan your code on every pull request and flag risky changes before they go live.
