What is Hexo?

Hexo is a fast, simple, and powerful blog framework powered by Node.js. While slightly older than some modern contenders, it remains a robust choice, particularly popular for creating blogs where build speed and simplicity are paramount. It is now considered a Legacy option, with development activity slowing down compared to modern frameworks.

Hexo parses Markdown files and generates static HTML files using a beautiful theme system. It is one of the most efficient generators when dealing with thousands of pages.

Key Features

1. Blazing Fast

Hexo is designed to be extremely fast. It can generate hundreds of files in seconds thanks to its efficient Node.js core. This makes it suitable for very large blogs that might slow down other generators.

2. One-Command Deployment

Hexo has a strong deployment system. With a single command (hexo deploy), you can deploy your site to GitHub Pages, Heroku, or Netlify, streamlining the publishing workflow.

3. Powerful Plugin System

Like Jekyll and WordPress, Hexo has a rich plugin system (accessible via npm) that can extend functionality with SEO tools, sitemap generators, and various template engines (EJS, Pug, Haml).

4. Markdown Support

It supports GitHub Flavored Markdown and most standard Markdown features, making it compatible with most writing workflows.
