Preflight.sh is a CLI tool that scans your codebase for common production mistakes before deployment, catching issues like leaked secrets, broken configurations, expired SSL certificates, missing SEO tags, and security gaps. With 70+ preconfigured service checks, it provides instant feedback on launch readiness without requiring accounts or complex setups.
Key benefits include:
- Comprehensive Pre-deployment Scans: Checks environment variable parity, health endpoints, SSL validity, security headers (HSTS/CSP), SEO metadata, service configurations, and 70+ integrations
- Developer-First Workflow: Run locally via simple CLI commands (preflight init + preflight scan) or integrate into CI/CD pipelines/GitHub Actions
- Instant Readiness Report: Clear visual output showing passed checks, warnings, and failures with actionable insights
- Service-Specific Validation: Verifies proper configuration for payments (Stripe/PayPal), analytics (Google/Plausible), error tracking (Sentry/Datadog), email (SendGrid/Mailgun), and more
- Privacy-Focused: Runs entirely locally without sending code to external servers or requiring accounts
Perfect for developers and DevOps teams who want to automate quality checks and prevent embarrassing production failures caused by overlooked configuration errors.
