What problem does it solve?

This Skill removes the need to test site performance one URL at a time by running Lighthouse across many pages and consolidating the results into one actionable audit.

Core Features & Use Cases

Multi-page auditing: Crawl and measure many routes on a site instead of a single landing page.
Aggregated reporting: Combine performance, accessibility, best practices, and SEO scores into a concise site-wide view.
Practical use cases: Use it for large-site regression checks after deploys, local Core Web Vitals measurement, and offline or restricted-environment audits.

FAQPage Schema

How do I run a Lighthouse audit across an entire website instead of one page at a time?▼

Multi-page auditing crawls and measures many routes on a site, consolidating performance, accessibility, best practices, and SEO scores into a single aggregated report. This removes the need to test site performance one URL at a time.

Can I use Lighthouse for CI regression checks after website deploys?▼

Yes, Lighthouse regression checks are supported for large sites after deploys. The process handles subprocess timeout management and parses the ci-result.json output to verify Core Web Vitals and multi-page SEO validation have not degraded.

What do I need to run multi-page Lighthouse audits locally?▼

You need Node 18+ and the unlighthouse-cli package installed. The environment must support subprocess execution for crawling routes and generating the aggregated site-wide performance report.

How does aggregated Lighthouse reporting work for large-site performance reviews?▼

Aggregated reporting combines route-level Lighthouse results into a concise site-wide view. It consolidates performance, accessibility, best practices, and SEO scores from every crawled page into one actionable audit report.

Does this Lighthouse audit approach work in offline or restricted environments?▼

Yes, offline and restricted-environment audits are explicitly supported use cases. The process includes URL safety checks and subprocess timeout handling to ensure reliable execution when measuring local Core Web Vitals.

What is the best way to validate Core Web Vitals across multiple site routes?▼

Use unlighthouse-cli to crawl and measure many routes on your site. It aggregates route-level Core Web Vitals measurements into a single report, providing a prioritized summary of main issues and fixes.
