How heavy the HTML document is, and how many resources it pulls in.
Free, no signup. We fetch the page once and read what your server sends back.
This measures the HTML document rather than the fully loaded page. Heavy HTML is a specific signal: it usually means inline styles, an inline data blob, or a page builder writing enormous markup.
For the HTML document, under about 100KB is comfortable. The full page including images is a different question and usually dominated by images.
Through speed, yes. Heavier pages load slower, particularly on mobile connections, and speed feeds Core Web Vitals.
Inline styles, inline SVG, base64 images embedded in the markup, or a builder that wraps everything in several nested divs with generated class names.
No. It reports the HTML document only, plus counts of what that document references.
