Static site generators (SSGs) are software engines that use text input files (such as Markdown, reStructuredText, AsciiDoc and JSON) to generate static web pages.[1] Static sites generated by static site generators do not require a backend after site generation, making them first-class citizens on content delivery networks (CDNs). Some of the most popular static site generators are Jekyll, Hugo, Next.js (JavaScript).[2][3] SSGs are typically for rarely-changing, informative content, such as product pages, news articles, software documentation, and blogs.
