Core Web Vitals are a set of user-facing metrics related to speed, responsiveness, and visual stability, to help site owners measure user experience on the web.

SEOSLY’s Olga Zarzeczna has published a guide called ‘Tools To Measure Core Web Vitals’.

She says, Here are 17 different tools you can use to measure Core Web Vitals both in the lab and in the field. Note that all the tools to measure Core Web Vitals rely on either Google Chrome, CrUX, or both.

1: Google PageSpeed Insights

Google PageSpeed Insights (PSI) is the number one tool when it comes to the measurement and assessment of Core Web Vitals. PSI is powered by both Lighthouse and Chrome UX Report, so it provides both the lab and the field data on both mobile and desktop devices. In addition to giving you an overview of field data coming from real-world users (CrUX), PageSpeed Insights also provides specific recommendations on how to improve the performance of the site (Lighthouse). PSI works on a per-page basis.
