The hook
A page can pass a quick desktop smoke test and still lose users on mobile because the payload is too heavy or the page waits on too many vendors.

FixWeb reads browser resource timing after render and groups resources by initiator type, transfer size, and first-party vs third-party origin.
The blast radius
Heavy scripts and third-party tags commonly degrade LCP and INP, while excess fonts and images add bandwidth and layout work.

The rendered crawl records approximate transfer bytes plus script, stylesheet, image, font, and third-party counts for each page.
Ironclad defenses
Set performance budgets, remove unused vendors, split and defer JavaScript, compress assets, cache immutable files, and optimize the likely LCP image.
