This URL redirects to https://microsoft.github.io/TypeChat/.

A trailing slash only, so both forms are treated as one site rather than two — one history, measured once. Lighthouse follows the redirect, so the numbers below describe the canonical page; the only cost is an extra hop on each run.

Stack

Detected on the same page load as the accessibility pass — the generator from <meta name="generator"> or the shape of the page, the host from response headers.

What LCP is made of observed, unthrottled

A flat LCP number tells you something regressed. The subparts tell you whether it was the server, resource discovery, the download, or rendering.

Measured on the trace before throttling is modelled, so these are real durations that will not sum to the 1.06 s above — that figure is a simulation of the same load on a slow phone and connection. Read these for the proportions: which phase dominates.

element render delay 47 ms

time to first byte 26 ms

Lab vs field

Lab LCP 1.06 s · field p75 1.77 s · real users are 1.67× slower than the lab. A gap this wide usually means real users are on slower devices or networks than the simulated ones — the lab number is flattering you.

Field history 25 weeks

Weekly p75 from the CrUX History API, backfilled in a single request.
