Lighthouse is available under Scanner → Lighthouse. It uses the Google PageSpeed Insights API to analyse one public page URL and returns category scores plus accessibility audit details. In older documentation this workflow was named Speed Core Web Vital. In the current product, use Lighthouse. Lighthouse results stay on this tab. They are not sent to Fix Hub — Fix Hub shows Scanner findings only.

​
Steps

  1. Configure the Google PageSpeed API key in AI Foundation → AI Features → General Settings.
  2. Open AI Accessibility.
  3. Select the page whose frontend URL should be tested.
  4. Open Scanner → Lighthouse.
  5. Click Run Lighthouse Scan and wait for results.
  6. Review category scores and accessibility audits.
  7. Review failed / manual audits on this Lighthouse results view (not in Fix Hub).

​
What you get

  • Category scores: Performance, Accessibility, Best Practices, SEO
  • Accessibility Health Score gauge
  • Failed / passed / manual / not-applicable audits
  • Audit rows you can open for detail
Lighthouse analyses one URL per run. It is not a multi-page tree scan like the Scanner.

​
Important notes

  • Only a public URL will work. Google PageSpeed cannot crawl .ddev.site or localhost. Point Site Settings at a public staging URL when you need Lighthouse locally.
  • Without a PageSpeed API key, Lighthouse cannot run.
  • A high accessibility score is a health indicator, not a WCAG conformance proof.
  • For local HTML checks without a public URL, use the Scanner instead.
