About LazySizes

LazySizes is a JavaScript library used to delay the loading of images (iframes, scripts, etc) until they come into view.

How we audit LazySizes

We measure the detected version against LazySizes's release history and grade the surrounding stack with a Lighthouse-grade quality audit. Weak or outdated links weigh more - one risky dependency can pull the whole score down.
