What it is
Lighthouse, built into Chrome devtools, scores any page on performance, accessibility, best practices and SEO, then lists concrete fixes. It's how I sanity-check Core Web Vitals before and after optimizing a site.
Extension Performance SEO Audit
Why I use it
I run Lighthouse in incognito to avoid extensions skewing the score, then chase the biggest LCP and CLS wins first.
