Stop embarrassing yourself in production.
Preflight is a command-line tool that scans your codebase for launch readiness before you ship. It finds missing configuration, integration issues, security concerns, SEO metadata gaps, and other common mistakes that break production deploys. Scanning runs on your machine, and no account is needed. MIT licensed.
