Hugo vs Jekyll vs MkDocs vs Docusaurus: Picking a Markdown Site Generator

A static site generator does one trick: it turns a folder of markdown files into a complete website. The four big names all do that trick well, which is exactly why choosing between them is confusing. The real differences are speed, templating, and what each one assumes you're building. Here's the short version, then the reasoning.

The short version: blog or general site → Hugo; GitHub Pages with zero setup → Jekyll; project documentation → MkDocs; documentation for a product with a React team → Docusaurus.

Hugo: speed as a feature

Hugo builds sites in milliseconds — a thousand-page site compiles before you've switched windows. That sounds like a benchmark flex until you've worked with live reload on a large site: instant builds change how you write. It ships as a single binary (no runtime to install), and its theme ecosystem covers blogs, portfolios, and company sites.

The cost: Hugo's Go templating is the least friendly of the four when you need custom layouts. Use a theme happily; expect a learning curve the day you fight one.

Jekyll: the GitHub Pages default

Jekyll's superpower is that GitHub Pages builds it automatically — push markdown to a repository and the site updates, no CI configuration, no build artifacts to manage, free hosting included. Eighteen years of themes and plugins mean solved problems everywhere.

The cost: Ruby. Local development needs a Ruby environment, builds slow down as sites grow, and the project's energy has visibly shifted to newer tools. Pick it for the Pages integration, not for the technology.

MkDocs: documentation without ceremony

MkDocs assumes you're documenting software: a docs/ folder of markdown plus one YAML file becomes a searchable documentation site. With the Material theme — practically a standard at this point — you get navigation, search, dark mode, and admonitions with zero design work. Python developers get bonus integration with docstring tooling.

The cost: it's docs-shaped. Blogs and marketing pages fight the structure.

Docusaurus: docs with React underneath

Docusaurus (from Meta) is also docs-first but bets on MDX — markdown with embedded React components. That buys interactive examples, versioned docs for multiple releases, and localization out of the box. If your product needs docs for v2 and v3 in three languages, this is the one designed for that problem.

The cost: a Node build chain and React knowledge when anything goes wrong. Overkill for a README-plus site.

What they all share

Every one of them consumes standard markdown with YAML front matter, which means the content you write today is portable across all four tomorrow — migrations between SSGs are template work, not content rewrites. Tables, task lists, and code fences follow the extended syntax rules.

Whichever you pick, the writing loop is identical: draft the page in markdown — a live-preview editor shows exactly what the generator will render — commit, push, deployed. The generator is plumbing. The markdown is the asset.
