How it works

Four steps. One pasted URL away.

01

Enter a URL

We load your real page, not a synthetic clone.

02

Lab metrics captured

LCP, CLS, INP, TBT and TTFB measured from a real render.

03

Bottlenecks isolated

Heavy images, render-blocking scripts and layout shifts traced to source.

04

Ranked by impact

The one change that drops LCP a full second comes first.

Built by people who shipped and broke things

What runs under the hood.

Core Web Vitals

The metrics Google ranks on, measured the way Google measures them.

Render-blocking traced

Scripts and styles delaying first paint, named and located.

Image weight

Unoptimized hero images are the top offender in AI-built apps. We catch them.

Impact-ordered

Effort where it counts, not a wall of yellow warnings.
