You will get an extra tab called GPSI on each individual URL that you test.

GPSI vs Lighthouse

GPSI runs Lighthouse in the backend. You can see which Lighthouse version in the HTML produced by the plugin. The plugin collects accessibility, seo, pwa, best-practices and performance scores.

Data sent to Graphite/InfluxDB

By default the plugin sends the GSPI score for the tested page for the five categories: accessibility, seo, pwa, best-practices and performance.

It also sends the loadingExperience for the page. That includes the actual percentile for First Contentful Paint and First Input Delay and the percentage of fast/moderate/slow users.

And it also sends a summary on domain level for the loading experience, meaning you can keep track of those metrics by running the plugin once a day.
