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
| Command | Effect |
|---|---|
/seo unlighthouse <url> | Mobile audit, up to 200 routes, JSON+HTML report in a temp dir |
/seo unlighthouse <url> --device desktop | Desktop form factor |
/seo unlighthouse <url> --max-routes 50 --output-dir ./reports | Cap + 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).
