Performance

Make your site faster

Enter a URL. We fetch the page, measure response times and transfer size, audit render-blocking assets, and rate performance, accessibility, best practices, and SEO from 1–10.

Checks run from this server over HTTP — no browser or third-party API required. Only analyze sites you own or are authorized to test.
