This page is designed to help you find out whether PreFlight Scan is good and if it is the right choice for you.
Pre-launch check for AI-built apps: 65 read-only checks on your live site covering security, speed, search, email setup and accessibility. The first scan is free and shows your top 3 fixes.
PreFlight checks your app the way any visitor could see it, before you launch. It runs 65 checks against your live site. They look for exposed secret keys and files, open admin and debug pages, HTTPS and certificate problems, missing security headers, cookie and cross-site settings, home-page speed, search visibility, page titles, descriptions and broken links, email sender DNS records (SPF, DMARC, common DKIM names), and accessibility basics. PreFlight also checks whether your Supabase or Firebase tables and storage can be read while signed out. That check is read-only.
Paste a link and confirm it's your site, or that you have permission to scan it. Results take about a minute. You'll see how many of the 65 checks you pass, plain-English findings sorted by severity, and your top 3 fixes for free. Each fix includes a prompt you can paste into your AI builder or editor. When PreFlight finds a secret key, it never shows any part of the key. It shows only the file and line.
The scan is passive. It uses only GET/HEAD requests and public DNS lookups. It doesn't log in, guess passwords, submit forms or change anything. PreFlight runs automated, best-effort checks. It's not a penetration test, audit or compliance certification.
