This site, measured.

A frontend engineer’s site should be able to prove its own performance, not just claim it. These are this page’s Core Web Vitals, measured live in your browser as you read.

LCP

…

Largest Contentful Paint

when the main content appears

INP

…

Interaction to Next Paint

how fast it responds to input

CLS

…

Cumulative Layout Shift

how much the layout jumps

FCP

…

First Contentful Paint

first pixels painted

TTFB

…

Time to First Byte

server response latency

Measured live, in your browser, as you load this page. Values settle after a moment and after you interact (INP needs a click or key press). These are real field metrics for this site, not a lab score screenshot.
