Read the comparison
You see both screenshots, a verdict, and speed side by side (main content, first content, layout shift, busy time and full load), plus checks for sideways scrolling, small text, small tap targets, the viewport tag and content missing on phones.

Good to know
- If a timing shows a dash, the browser didn't report it for the background tab. Run the comparison again with the page visible.
