Eleventy High Performance Blog

Eleventy High Performance Blog is a production-ready blog starter built on Eleventy (11ty) that treats performance and accessibility as first-class features rather than afterthoughts. It ships with an opinionated set of best practices, pre-rendered HTML, minimal JavaScript, and carefully tuned CSS, so pages are fast even on slow networks and low-end devices. The starter is organized for excellent Core Web Vitals by default, emphasizing fast Largest Contentful Paint, stable layout, and minimal blocking resources. It includes responsive image pipelines, modern font loading strategies, and progressive enhancement so content remains usable without client-side scripts. The structure also encourages good content semantics and metadata, making it easy to achieve top Lighthouse scores across performance, SEO, and accessibility. Because it’s a static-site approach with Eleventy’s flexible templating, teams can customize layouts and content models while preserving the starter’s performance.
