Scan your Replit site before you ship
Replit Agent can build and deploy apps in many stacks. Deployments are reachable on a replit.app domain or your own, so what's public is whatever your server sends to the browser.

Common Replit launch issues
🛡️ Security
- Replit Secrets keep keys out of your code, but a key can still leak if front-end code reads it or the server echoes it into a page.
- Security headers depend on your framework; a plain Express or Flask server sends almost none by default.
- Session cookies set by your own server code may be missing Secure or HttpOnly flags.
🔎 SEO
- Apps built as single-page front ends may be blank to non-JS crawlers.
- Titles and meta descriptions are often left at framework defaults.
⚡ Performance
- Slow server responses can come from heavy work done on each request; check response time after deploying.
