Eleventy AI readiness statistics

In November 2026, we could only tell which sites run on Eleventy where our scanner could read the page, so this page covers those sites and says nothing about how many turned our scanner away.

All sites on the State of the Web

How Eleventy sites land

Every page we read gets a score out of 100, the number at the top of its report (how scoring works). Each row is a range of scores. Where too few sites score in the lowest ranges, they are joined into one row.

Not enough sites yet There are not enough sites yet to split them by score.

A platform is only detectable on a page our scanner could read, so these shares are of the Eleventy sites we could read.

What Eleventy sites get right and wrong

Every check, Eleventy against all sites

Share of sites that pass each check, over the sites the check applies to. The Gap column is the difference in percentage points between the two shares; a dash means not enough sites yet.
