description Eleventy (11ty) Overview
Eleventy is a simpler, more flexible alternative to heavy framework-based generators. It is built on Node.js and is completely framework-agnostic, allowing you to use almost any templating language, including Nunjucks, Liquid, Handlebars, and even plain HTML. Eleventy doesn't force you into a specific component model, making it perfect for developers who want full control over their markup. It is incredibly fast and has a very low learning curve.
It is the preferred choice for developers who value simplicity and want to avoid the 'JavaScript fatigue' associated with modern frameworks.
