Eleventy Static Generator

Eleventy is a simpler static site generator created by Zach Leatherman at Netlify in 2018, designed as a lightweight, zero-configuration alternative to Jekyll and Hugo, using JavaScript and Node.js to transform template files into static HTML without bundling any client-side JavaScript by default, supporting eleven template languages including Liquid, Nunjucks, Handlebars, Mustache, EJS, Haml, Pug, JavaScript template literals, and HTML, adopted by Google Chrome team, web.dev, and thousands of blogs and documentation sites seeking maximum performance. The zero-JavaScript philosophy means the generated sites ship no client-side framework, no hydration scripts, and no unnecessary JavaScript bundles, producing extremely fast page loads with minimal overhead, with the framework adding JavaScript only when explicitly chosen by the developer through optional integrations, making it ideal for content-focused sites including blogs, portfolios, and documentation where performance and accessibility are prioritized over interactive complexity. The template language flexibility enables mixing different template languages within the same project, with each template file using its own language, enabling developers to choose the best language for each page or component, while custom collections filter, sort, and group content by tags, dates, or custom criteria, providing powerful content organization without database dependencies. The data cascade system merges data from global data files, directory-level data files, template-specific frontmatter, and computed data, with later sources overriding earlier ones, enabling flexible content management. The pagination system generates multiple pages from a single template. The plugins extend with image optimization, syntax highlighting, and RSS generation. Designed for web developers prioritizing performance.
