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

The same URL in a different form — a trailing slash — so both are treated as one site rather than two: one history, measured once. Lighthouse follows the redirect, so the numbers below describe the page actually served; the only cost is an extra hop on each run.

The measuring machine was faster than most in this project.

Lighthouse benchmark index was 4,189, 69% faster than this project's median of 2,486. CPU-bound metrics — TBT, TTI, main thread work — are affected by this and may have moved without the site changing at all.

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 (2026-09-05 → 2026-10-02), origin-level.

LCP Subparts LAB Unthrottled

The subparts attribute LCP to your server, resource discovery, download, or rendering. Note that the Lab LCP shown above is a simulated throttled estimate.

element render delay 37 ms
time to first byte 23 ms

LCP LAB Simulated vs LCP FIELD

Lab 1.06 s
Field p75 1.52 s

The lab LCP is 0.7× the field p75 — real users likely have below-average hardware or network connectivity. A gap this wide usually means real users are on slower devices or networks than the simulated ones — the lab number is flattering you.
