Jekyll is a static site generator written in Ruby by Tom Preston-Werner.

[5] As of 2017[update] Jekyll was ranked the most popular static site generator, largely due to its adoption by GitHub.

The Jekyll project on GitHub continues to be updated and releases are being made for bug fixes.

Jekyll renders Markdown or Textile and Liquid templates, and produces a complete, static website ready to be served by Apache HTTP Server, Nginx or another web server.

Instead Jekyll supports loading content from YAML, JSON, CSV, and TSV files into the Liquid templating system.
