Eleventy, a fast static site generator

Eleventy, often stylized as "11ty," is a static site generator (SSG) that helps developers build websites. It is an open-source tool written in JavaScript and designed to be simple, flexible, and extensible. Eleventy takes data and templates and generates a static HTML-based website, which can be deployed to a web server.

Eleventy supports incremental builds, meaning that it only rebuilds the parts of your site that have changed. This significantly reduces the time it takes to regenerate your site when you make updates, especially for larger projects.
