Today we’re launching a new free tool: Compare Website Speed.
Drop in up to 5 sites and get a ranked leaderboard built from real Chrome user data, sourced from the Chrome User Experience Report. Every comparison gets a permalink and an auto-generated share card that names the winner.

An example share card comparing five major US retailers. ikea.com leads on Core Web Vitals with a score of 93, ahead of amazon.com (80), walmart.com (74), target.com (72) and uniqlo.com (66). Every comparison generates one of these automatically.
Use it to:
- See who’s fastest among any group of sites: competitors, alternatives or your own portfolio.
- Compare Largest Contentful Paint, Cumulative Layout Shift and Interaction to Next Paint side-by-side, using real user data from the last 28 days.
- Share the result with a permalink, or save the share card as a PNG.
