Eleventy

Eleventy (11ty) is a popular open-source static site generator written in JavaScript. It is a simplistic zero-config framework meant for content-heavy websites such as blogs, e-commerce sites and documentation sites.

One of Eleventy's biggest strengths is its agnostic approach to templating. Where other static site generators such as Gatsby are built on top of React, which uses JSX/TSX, Eleventy provides a variety of popular template languages such HTML, Markdown, EJS (Embedded JavaScript) and Liquid, to name a few. It is also possible to add custom template parsers.
