Popular Static Site Generators. Source: Devopedia 2018.

A static site generator is an application that uses plain text files rather than a database as the content repository and builds HTML files by applying themes, layouts and templates to them.

The generated static site files are delivered to the end user exactly as they are on the server. Hence, there is no server-side language or database. The generated files are HTML, CSS and JavaScript, served with graphic files (jpeg, gif, svg, webgl) and data formats ( JSON or XML).

Static sites offer several advantages in speed, security and scalability over dynamic sites (Content Management Systems).
