Eleventy is a static site generator that transforms a directory of templates of varying types into HTML. It solves the problem of building static websites by accepting multiple template formats—HTML, Markdown, JavaScript, Liquid, and Nunjucks as core options, with additional support through addons for WebC, Sass, Vue, Svelte, TypeScript, JSX, and others. The tool processes these templates directly without requiring complex configuration, making it accessible for developers who want straightforward site generation without the overhead of heavier frameworks.
Eleventy suits developers building blogs, documentation sites, and other static content who prefer working in JavaScript and want flexibility in template language choice. It works well for projects where you need to mix different template formats within the same site or want to avoid vendor lock-in to a specific templating system. The tool is positioned as a simpler alternative to Jekyll, targeting those already comfortable with Node.js tooling.
The project maintains multiple test suites covering different environments: a primary JavaScript test suite using ava, a secondary Node.js test runner suite, and browser-mode tests with Vitest. The team runs continuous integration on GitHub Actions and tracks code coverage statistics. The project uses a community roadmap with feature requests and bug tracking organized through GitHub discussions and issues, allowing users to vote on priorities.
