Jekyll
Jekyll is a static site generator written in Ruby that transforms plain text into static websites and blogs. It takes content written in Markdown, Textile, or HTML, processes it through Liquid templates, and generates a complete, ready-to-publish static site. It is commonly used for blogs, documentation sites, and personal portfolios due to its simplicity and integration with GitHub Pages.
Developers should learn Jekyll when they need to build fast, secure, and low-maintenance static websites without the overhead of a database or server-side processing. It is ideal for blogs, project documentation, and personal websites where content is mostly static and can be version-controlled with Git. Its seamless integration with GitHub Pages makes it a popular choice for hosting free, automated deployments directly from a repository.
