Jekyll
What is Jekyll?
Jekyll is an open-source static site generator (web content management / static site generation) written in Ruby that converts plain text files into structured static websites and blogs.
- Static site generation from Markdown, HTML, and other text formats (static site generation)
- Template-based layouts using the Liquid templating language (templating)
- Content organization via collections, posts, pages, and data files (content management)
- Plugin, theme, and configuration system for customization and reuse (extensibility / theming)
- Integration path for deployment on GitHub Pages and other static hosting platforms (static web hosting enablement)

More About Jekyll
Jekyll is a static site generator (static site generation) built in Ruby that converts a directory of text files, templates, and configuration into a static website composed of HTML, CSS, and other assets. It targets use cases where content can be generated at build time instead of dynamically on each request, including blogs, documentation sites, marketing sites, and project homepages. Jekyll removes reliance on a traditional database-backed content management system by compiling content into static files that can be served by any standard web server or static hosting service.
The core workflow centers on a project directory structure (content management) that includes configuration, layouts, posts, pages, collections, and assets. Content is typically authored in Markdown or HTML, with optional YAML front matter that defines metadata such as titles, dates, and layout selection. Jekyll processes this content through the Liquid templating language (templating), enabling layout inheritance, includes, variables, and filters. During a build, Jekyll generates a complete static site into an output directory, resolving templates, permalinks, and asset paths according to the configuration.
Jekyll provides a configuration-driven model via a central configuration file (site configuration) that controls site metadata, URL structure, plugin activation, and build options. Collections and data files (structured content management) allow users to define custom content types and feed them into templates through structured YAML, JSON, or CSV data. A built-in development server with automatic regeneration (local development tooling) supports local preview of content and templates as files change, aligning with common developer workflows.
Enterprises and institutions often use Jekyll to publish documentation, internal knowledge bases, and public web properties (documentation and web publishing) where static content delivery is appropriate. Because Jekyll outputs static assets, it can be deployed on content delivery networks and static hosting platforms (static web hosting), which can simplify scaling, caching, and security postures compared to dynamic systems. Jekyll’s compatibility with GitHub Pages (CI-integrated static hosting) enables version-controlled content workflows where site content, templates, and configuration are stored in Git repositories and built automatically on commit.
Jekyll supports themes and plugins (extensibility) that extend layout, styling, and functionality while keeping site content separated from presentation. Themes package layouts, includes, and assets for reuse across multiple sites, while plugins can add generators, tags, filters, and other build-time logic, subject to the execution environment’s plugin policies. This ecosystem positioning places Jekyll within categories such as static site generation, developer-centric content management, and documentation site tooling, commonly integrated into broader DevOps, Continuous Integration and Continuous Deployment (CI/CD), and Git-based content workflows.
