Which metrics do you collect?

LCP, INP, CLS, FCP, and TTFB, plus frame rate.

Why does PageSpeed Insights show no data for my site?

Google's field data only covers Chrome users on sites with enough traffic. Databuddy measures every visit to your site.

Do Safari and Firefox report vitals?

Current versions report LCP, INP, FCP, and TTFB. CLS comes from Chromium browsers.

Not for fixed thresholds yet. On Business and Scale, Databunny flags pages whose LCP or INP got much worse than the week before.

Which plans include it?

Every plan, including free. Each metric reading counts as one event.
