The physics floor

How fast it could be, not just how fast it is.

Laptime computes the theoretical minimum LCP from your round-trip time and resource sizes, then splits LCP into TTFB, load delay, load time and render delay to show where the gap sits.

laptime.dev - Anywhere
Anywhere

One report card, from the toolbar or the pipeline.

Performance, security, privacy and SEO in the same report. The browser extension scans any tab and keeps running after the popup closes; the CI integration gates every deploy.
