This data is 4d old.

Sites are measured on a rolling schedule, so figures here are the newest successful measurement rather than a reading taken just now. Comparisons against other sites may span different points in time.

Lab data is measured using Lighthouse, Mobile mode unless otherwise specified. Field data is reported from Chrome UX Report (using p75 measurements).

Metrics LAB FIELD

Core Web Vitals: passing 3 of 3 assessed from real Chrome users.

Field figures are the p75 across real Chrome users over a 28-day trailing window (2026-09-09 → 2026-10-06), url-level.

LCP Subparts LAB Throttled

The subparts attribute LCP to your server, resource discovery, download, or rendering. They come from one throttled load, the same one as the filmstrip, so they add up to that load’s LCP rather than the simulated Lab LCP above.

element render delay 1.88 s

time to first byte 569 ms

LCP LAB Simulated vs LCP FIELD

Lab 5.03 s

Field p75 1.99 s

The lab LCP is 2.53× the field p75 — real users likely have above-average hardware or network connectivity.

The same load, photographed twice at 412×823: once with scripts disabled, once as rendered.

2.3% of pixels differ — they are nearly identical. A shifted layout counts as difference, so a <noscript> banner alone can account for a large figure.
