# Unlighthouse

> Unlighthouse is an MIT-licensed Node.js CLI (v0.19.1, Oct 2026) that discovers a site's pages and runs Google Lighthouse on each, showing performance, accessibility, best-practice and SEO scores in a local web UI. Run with \`npx unlighthouse --site \<url\>\`; needs Node 22.18+ and uses system Chrome or downloads Chromium. No paid services. It audits pages only: no keyword data, rank tracking or backlinks. Hardware needs are not documented.
