seo-unlighthouse

Run Lighthouse against every URL on a site (up to a configurable cap) and aggregate the results. Useful when:

  • PageSpeed Insights' free quota (25k QPD) isn't enough for a large site.
  • You want offline / local CWV measurement (CI integration, restricted environments).
  • You need a quick site-wide regression check after a deploy.

Prerequisites

  • Run extensions/unlighthouse/install.sh (no API key needed).
  • Node 18+ on $PATH.

Routing

CommandEffect
/seo unlighthouse <url>Mobile audit, up to 200 routes, JSON+HTML report in a temp dir
/seo unlighthouse <url> --device desktopDesktop form factor
/seo unlighthouse <url> --max-routes 50 --output-dir ./reportsCap + persist

All flags forward to scripts/unlighthouse_run.py which handles url_safety pre-flight and subprocess timeout management.

Output handling

The wrapper reads ci-result.json from the Unlighthouse output dir and returns it parsed. Aggregate fields:

  • score.performance (median across audited routes)
  • score.accessibility, score.bestPractices, score.seo
  • Per-route breakdown is available in <output_dir>/ci-result.json

Cross-skill delegation

  • For single-URL field data (CrUX), use seo-google psi / seo-google crux.
  • For LCP subpart decomposition on slow pages, use the scripts/lcp_subparts.py workflow (Phase C).
