Eleventy is a free static site generator that compiles templates into HTML. It starts without configuration, while allowing more flexible configuration as a project develops. Content can come from Markdown, and templates can use formats including HTML, JavaScript, Liquid, Nunjucks, TypeScript, JSX, MDX, and Sass. Eleventy does not require a JavaScript framework and produces zero client-side JavaScript by default. It can work with an existing directory structure, so teams can convert selected templates rather than changing everything at once. The product supports a local preview server, CMS integrations, and multilingual content. Eleventy requires JavaScript and recommends Node.js version 18 or newer. Its documentation provides setup commands for macOS, Linux, Windows, npm, pnpm, and Yarn. The project says it is probably not right for single-page applications, given its default approach and full-page navigation. Eleventy is available for Linux, macOS, Windows, and self-hosted use under an MIT license.
