Jekyll is a simple, blog-aware static site generator written in Ruby by Tom Preston-Werner, GitHub co-founder. It transforms plain text — Markdown, Liquid templates, HTML, CSS — into a static website ready to serve from any web host.
Jekyll is the original engine behind GitHub Pages and has powered countless blogs, documentation sites, and personal websites since 2008. Its plugin ecosystem and theme support remain robust.
