Page Builder Lazyload Images (SISL fork)
Adds loading="lazy" to Page Builder images — better LCP and Core Web Vitals, no code. Runs on 2.4.9.
Images added through Magento 2 Page Builder load eagerly by default — the browser fetches all of them, including below-the-fold ones, before rendering the page. That hurts LCP and Core Web Vitals, especially on mobile.
This module adds a per-image loading="lazy" toggle in Page Builder — a native browser attribute, no JavaScript, no code changes. The original was abandoned (no composer requirements). SISL fork: fixed requirements, runs on Magento 2.4.9 / PHP 8.4. Free, open source.
