Octolens

Security & Configuration Auditing for GitHub Repositories

OctoLens is a CLI tool that scans and analyzes GitHub repositories — individually, in bulk, or across entire organizations — to produce detailed reports on:

• Security posture – vulnerabilities, secret leaks, insecure configurations.
• Configuration compliance – repository settings, governance rules, industry standards.
• Best practices – branch protection, workflow safety, and repository hygiene.

Whether you’re running a compliance audit, reviewing security health, or ensuring consistent configuration across teams, OctoLens delivers clear, actionable insights.

✨ Features

• 🔍 Full-Org Scanning – Audit one, multiple, or all repositories in a GitHub organization.
• 📋 Detailed Reports – Export findings in human-readable or machine-consumable formats (JSON, Markdown, HTML).
• 🛡 Security Checks – Detect risky settings, missing protections, and potential vulnerabilities.
• ⚙ Configuration Review – Validate settings against good practices and compliance requirements.
• 🧭 Customizable Rules – Extend or override checks to match your own standards.

🚀 Installation

# Install globally via npm
npm install -g @sheplu/octolens
