# Jekyll — The Ruby Static Site Generator Behind GitHub Pages > Jekyll transforms plain text files into static websites and blogs. It reads Markdown and Liquid templates, generates a complete site at build time, and powers GitHub Pages natively. ## Install Save as a script file and run: # Jekyll — The Ruby Static Site Generator Behind GitHub Pages ## Quick Use ```bash gem install bundler jekyll jekyll new my-site cd my-site bundle exec jekyll serve # Open http://localhost:4000 ``` ## Introduction Jekyll is a static site generator written in Ruby that converts Markdown, Liquid templates, and YAML front matter into a production-ready static website. Created by Tom Preston-Werner in 2008, it became the default engine behind GitHub Pages and remains one of the most widely deployed generators for blogs, documentation, and project sites. ## What Jekyll Does - Converts Markdown and HTML with Liquid templates into a static site - Supports YAML front matter for per-page metadata and layout selection - Provides a built-in development server with live reload - Generates a complete blog-aware site with posts, categories, and tags - Integrates directly with GitHub Pages for zero-config deployment ## Architecture Overview Jekyll reads source files from a project directory, parses YAML front matter, processes Liquid tags and filters, renders Markdown through kramdown (default), and writes the final HTML to a `_site` output folder. Plugins hook into the build lifecycle at generator, converter, or tag stages. The entire pipeline runs as a single Ruby process with no database or server-side runtime required. ## Self-Hosting & Configuration - Install Ruby 2.7+ and run `gem install jekyll bundler` - Configure site metadata, permalink style, and plugins in `_config.yml` - Place posts in `_posts/` using the `YYYY-MM-DD-title.md` naming convention - Add custom layouts under `_layouts/` and reusable partials under `_includes/` - Deploy by pushing `_site/` to any static host, or use GitHub Pages for automatic builds ## Key Features - Native GitHub Pages integration with automatic builds on push - Liquid templating with filters, includes, and layout inheritance - Extensive plugin ecosystem for SEO, feeds, sitemaps, and pagination - Incremental regeneration for fast rebuilds during development - Themes as gems that can be versioned and shared across projects ## Comparison with Similar Tools - **Hugo** — Written in Go, significantly faster builds, but uses a custom template syntax instead of Liquid - **Eleventy** — Node.js-based, more flexible with multiple template languages, less opinionated structure - **Pelican** — Python-based static generator, strong reStructuredText support, smaller plugin ecosystem - **Gatsby** — React-powered with GraphQL data layer, heavier build process, richer client-side interactivity - **Astro** — Modern component-based static generator supporting multiple UI frameworks, different mental model ## FAQ **Q: Is Jekyll still actively maintained?** A: Yes. The project continues to receive maintenance releases and security patches, and it remains the default GitHub Pages engine. **Q: Can Jekyll handle large sites with thousands of pages?** A: Jekyll can build large sites, though build times grow linearly. Incremental builds and caching help, but very large sites may benefit from Hugo or similar generators. **Q: Do I need Ruby knowledge to use Jekyll?** A: Basic usage requires no Ruby. Liquid templates and Markdown cover most needs. Ruby knowledge helps only when writing custom plugins. **Q: How does Jekyll compare to a CMS like WordPress?** A: Jekyll produces static files with no database or server runtime, resulting in faster page loads and simpler hosting. It trades WordPress's admin UI for a file-based workflow. ## Sources - https://github.com/jekyll/jekyll - https://jekyllrb.com/docs/ --- Source: https://tokrepo.com/en/workflows/7d9e2fd4-42fe-11f1-9bc6-00163e2b0d79 Author: Script Depot
