CrUX field data,plus deliveryhygiene evidence.

Available origin-level LCP, INP and CLS field data from the Chrome UX Report, plus static response and resource checks. ShipReady does not run a browser trace or attribute a metric to a specific cause.

How it works

Four steps. One pasted URL away.

01

Enter a URL

We load your real page, not a synthetic clone.

02

CrUX field data queried

When Google has a record for the final origin, we read poor LCP, CLS and INP p75 values.

03

Static signals inspected

Fetched headers, markup and resource evidence identify delivery signals worth investigating.

04

Evidence kept separate

Origin-level field metrics and static delivery signals retain their own evidence and limits.

Built by people who shipped and broke things

What runs under the hood.

Core Web Vitals

Available origin-level Chrome UX Report p75 data for LCP, INP and CLS — not a browser performance test.

Render-blocking evidence

Static script and stylesheet references that merit page-level investigation.

Image delivery evidence

Image response and dimension signals from fetched pages; they do not identify an LCP element.

Evidence-bounded

Findings distinguish field data from static delivery checks and their coverage limits.

Review your field and delivery evidence.
