Frequently Asked Questions

Everything you need to know about Preflight and how it can help you launch with confidence.

What exactly does Preflight check?

Preflight audits your site for security headers, meta tags, SEO, error handling, TLS/HTTPS configuration, authentication flows, cookie usage, core web vitals, external scripts, and common SaaS features.

How long does a scan take?

Most scans complete in under 60 seconds, depending on the complexity of your site and the current load on our systems.

Can I scan sites that are behind authentication?

Not in the current MVP. Support for authenticated scans is on our roadmap for a future release.

Do you store my website's data?

We only store the scan results and issues found. We don't store or cache your actual website content.

Can I integrate Preflight with my CI/CD pipeline?

This feature is planned for our Pro tier in a future update. Currently, scans are initiated manually from the dashboard.

How accurate are the scan results?

Preflight uses industry-standard tools and best practices to provide highly accurate results, but we recommend manual verification for critical issues.
