Why is this different from the score in my browser?
The graded score is the desktop run. Lighthouse 13.5.0 runs at Google through the PageSpeed Insights API on a desktop profile with no CPU or network throttling — close to what Chrome DevTools on a laptop, GTmetrix's default test and the PageSpeed API (which defaults to desktop) all measure, so this is the number you should be able to reproduce: run it yourself on PageSpeed Insights.
Google ranks on mobile. That run happens too, on an emulated mid-range Android with a 4× CPU slowdown and a throttled connection, and the same page routinely scores 30–50 points lower there. Neither number is wrong — they are different tests.
Lighthouse also varies a few points run to run on the same URL. Treat a trend across several scans as the signal, never a single digit.
Lab data: Google PageSpeed Insights (Lighthouse, desktop). Server probes (TTFB, compression, cache, headers) are measured separately from Vilnius, Lithuania (EU).

xSpeed is a WordPress plugin, so it can't automate GravCMS fixes — and that's fine. Every check below links its official guideline, and the machine-readable twin of this report gives an AI everything it needs to plan the work (7 checks name a concrete remediation):
Read the speed report at https://xspeedcache.com/scan/r/getgrav-org-774dc55f14.md — it lists every failing check with evidence and the official guideline for the fix. Produce a prioritized fix plan for my GravCMS site, apply what you can, then re-test by POSTing {"url":"https://getgrav.org/"} to https://xspeedcache.com/api/scan and compare the scores.Hosting is half of every score.
Whatever the stack — GravCMS included, the server behind it sets the floor on TTFB. xCloud — from the team behind xSpeed — hosts any platform (this site's own scanner runs on it), with agent/MCP access built in and bring-your-own-server pricing.

TTFB 379ms measured from Vilnius, Lithuania (EU) (best of 2 requests). This includes the network round trips between us and your origin, not just server time. Google measured your server responding in 4ms from its own network — the gap between the two numbers is distance, not your server.
The server rebuilds the page on every request. A page cache answers in 5–15ms.
