Hugo:
Hugo is a general-purpose website framework. Technically speaking, Hugo is a static site generator. This means that, unlike systems like WordPress, Ghost and Drupal, which run on your web server expensively building a page every time a visitor requests one, Hugo does the building when you create your content. Since websites are viewed far more often than they are edited, Hugo is optimized for website viewing while providing a great writing experience.
