PageSpeed Insights only audits one URL at a time, which makes comparing pages slow and repetitive. I built a small free tool that lets you run Lighthouse audits across multiple URLs and compare SEO, performance, and accessibility scores side-by-side. It uses the PageSpeed Insights API under the hood. Feedback and suggestions welcome. https://www.bulkaudits.com/
