What it is
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.
