# Preflight.sh

> Preflight is an open-source CLI that scans your codebase for launch readiness before you deploy: leaked secrets, security headers, SSL, SEO, broken configs, and 72 commonly misconfigured services, across every major framework and CMS. It runs locally or in CI and never sees your code.

Install: brew install preflightsh/preflight/preflight, npm install -g @preflightsh/preflight, go install github.com/preflightsh/preflight@latest, docker pull ghcr.io/preflightsh/preflight, or curl -sSL https://preflight.sh/install.sh | sh
Agent skill: npx --yes skills add preflightsh/preflight --skill preflight

## Docs
- [Getting started](https://preflight.sh/docs/index.md): Install Preflight, set it up in a project, and run your first launch-readiness scan.
- [Scanning](https://preflight.sh/docs/scanning.md): Every flag preflight scan takes, its JSON output, its exit codes and shell completions.
- [Checks](https://preflight.sh/docs/checks.md): What each Preflight check looks for, and the ID to use with --only, --skip and ignore.
- [Services](https://preflight.sh/docs/services.md): The 72 services Preflight detects and checks, by category, with the ID of each.
- [Configuration](https://preflight.sh/docs/configuration.md): Every key in preflight.yml: the project, its URLs, its services, each check's settings and the ignore list.
- [Ignoring checks](https://preflight.sh/docs/ignoring.md): Silence a check or service that doesn't apply, or allow one known secret without turning off the secrets scan.
- [CI](https://preflight.sh/docs/ci.md): Run Preflight on every pull request with GitHub Actions, using the install script, npm or Docker.
- [Agent skill](https://preflight.sh/docs/agent-skill.md): Install the Preflight skill so Claude Code, Cursor, Codex and other coding agents run scans and fix what they find.
- [Dashboard](https://preflight.sh/docs/dashboard.md): Publish scans to app.preflight.sh for a history of every run and AI fix suggestions for each finding.
- [Supported stacks](https://preflight.sh/docs/stacks.md): The frameworks, CMSs and static site generators Preflight detects.
