Hugo is a fast static website engine. It’s written in 
go (aka Golang) and developed by bep, spf13 and friends.
From What is Hugo:
Hugo is a general-purpose website framework. Technically speaking, Hugo is a static site generator. Unlike systems that dynamically build a page with each visitor request, Hugo builds pages when you create or update your content. Since websites are viewed far more often than they are edited, Hugo is designed to provide an optimal viewing experience for your website’s end users and an ideal writing experience for website authors.
Websites built with Hugo are extremely fast and secure. Hugo sites can be hosted anywhere, including Netlify, Heroku, GoDaddy, DreamHost, GitHub Pages, GitLab Pages, Surge, Aerobatic, Firebase, Google Cloud Storage, Amazon S3, Rackspace, Azure, and CloudFront and work well with CDNs. Hugo sites run without the need for a database or dependencies on expensive runtimes like Ruby, Python, or PHP.
Hugo offers native support for content written in markdown, and metadata (front matter) in TOML, YAML or JSON.
