A pre-launch checklist for your codebase

Everyone has shipped something broken. A missing env var, debug mode left on, an expired SSL cert, a leaked key. Preflight exists to catch that class of mistake before your users do.

It's a single command that scans your project for launch readiness: secrets, security headers, SSL, SEO, broken configs, and 70+ commonly misconfigured services, across every major framework and CMS. It runs locally or in CI, sees your code only on your machine, and never phones home.

Preflight is open source under the MIT license. The optional dashboard at app.preflight.sh adds run history and AI-powered fix suggestions, but the CLI stands on its own, no account required.
