Eleventy vs Jekyll

Eleventy is a free static site generator that compiles templates into HTML. It starts with zero configuration and also allows flexible configuration as project needs change. Content can come from Markdown, and templates can use HTML, JavaScript, WebC, Liquid, Nunjucks, Handlebars, Mustache, EJS, Haml, Pug, TypeScript, JSX, MDX, Sass, and custom formats. Eleventy does not require a JavaScript framework and produces zero client-side JavaScript by default. It can fit into an existing directory structure, letting teams convert selected templates rather than an entire site. The tool includes a local preview server, CMS integration, and multilingual support. It requires JavaScript and recommends Node.js version 18 or newer; quick-start commands are provided for macOS, Linux, and Windows, and for npm, pnpm, and Yarn. Its documentation says it probably is not the right tool for single-page applications, given its defaults and full-page navigation. Eleventy supports self-hosted use and is marked MIT licensed. The homepage reports a build time of 1.93 seconds for 4,000 Markdown files.

Jekyll is a free, open-source tool that turns plain text into static websites and blogs. It combines Markdown, Liquid, HTML, and CSS with layouts, producing static files ready for deployment. Blog features include permalinks, categories, pages, posts, and custom layouts. A plugin system with hooks can generate content and extend builds without changing Jekyll itself. Community-maintained themes provide templates and styles, and site content can override theme files. Generated sites may be deployed manually, through automation, or with third-party services. GitHub Pages is powered by Jekyll and offers free hosting with custom domain support. Jekyll supports Linux, macOS, Windows, and self-hosted use. Installation requires Ruby 2.7.0 or higher, RubyGems, GCC, and Make. Safe mode requires explicit plugin permission through a whitelist. A volunteer core team maintains the project.
