When I first started building technical docs, I thought any Static Site Generator (SSG) would do. But as my project grew from ten pages to over two hundred, I realized that the choice of hugo vs jekyll for documentation isn’t just about syntax—it’s about the developer experience and the ‘time to first render’.
If you’re just starting out, you might be wondering why use a static site generator in the first place. The answer is usually speed, security, and the ability to treat your documentation as code. But when it comes to the two heavyweights, Hugo and Jekyll, the tradeoff usually comes down to build speed versus ecosystem maturity.
Jekyll: The Reliable Veteran
Jekyll is the ‘old guard’ of the JAMstack. Because it’s the engine behind GitHub Pages, it has a level of integration that is hard to beat. In my experience, Jekyll is fantastic for smaller documentation sites where you want a ‘zero-config’ deployment to GitHub.
The Pros of Jekyll
- Deep GitHub Integration: Push your code, and your docs are live. No complex CI/CD pipelines required.
- Ruby Ecosystem: Access to a massive library of plugins for everything from SEO to sitemaps.
- Lower Learning Curve: Liquid templating is generally more intuitive for beginners than Hugo’s Go templates.
The Cons of Jekyll
- Build Speed: This is the dealbreaker. As your documentation grows, Jekyll’s build times increase linearly. I’ve seen sites with 500+ pages take several minutes to rebuild a single typo.
- Ruby Dependency: Installing Ruby and managing gems (Bundler) can be a nightmare on Windows machines.
Hugo: The Speed Demon
Hugo is written in Go and is famously fast. While Jekyll feels like a steady walk, Hugo feels like a teleport. For large-scale documentation, Hugo is often the only viable choice among the traditional SSGs.
The Pros of Hugo
- Insane Performance: Hugo can build thousands of pages in milliseconds. It removes the ‘wait and see’ loop during development.
- Single Binary: No Ruby, no Node.js, no dependencies. You download one executable, and you’re ready to go.
- Powerful Content Organization: Hugo’s ‘Sections’ and ‘Taxonomies’ make it incredibly easy to organize deeply nested documentation hierarchies.
The Cons of Hugo
- Steep Learning Curve: The Go templating language is powerful but can be cryptic. I spent my first three days just trying to figure out how to loop through a menu.
- Complex Configuration: While the binary is simple, the
hugo.tomlconfiguration can become a beast.

Feature Comparison Table
To give you a clear view of how these two stack up for documentation purposes, I’ve summarized the key differences below:
| Feature | Jekyll | Hugo |
|---|---|---|
| Build Speed | Slow (Ruby) | Blazing Fast (Go) |
| Installation | Complex (Ruby/Gems) | Simple (Single Binary) |
| Templating | Liquid (Easy) | Go Templates (Steep) |
| GitHub Pages | Native Support | Via GitHub Actions |
| Scalability | Low to Medium | Very High |
As shown in the table above, the choice usually hinges on whether you value ease of setup (Jekyll) or long-term scalability (Hugo). For those who prefer a modern JavaScript-based approach, deploying Astro to GitHub Pages is another excellent alternative that bridges the gap between speed and developer experience.
Use Cases: Which One Should You Pick?
Choose Jekyll if…
You are building a small-to-medium documentation site (under 100 pages), you are already comfortable with Ruby, or you want the absolute simplest deployment path to GitHub Pages without touching a YAML workflow file.
Choose Hugo if…
You are building a massive knowledge base, an API reference, or any site where you expect to have hundreds or thousands of pages. If you hate waiting for a build to finish, Hugo is your only choice.
My Final Verdict
In my professional experience, Hugo wins the battle for documentation. While Jekyll’s simplicity is tempting at the start, the friction of slow build times eventually outweighs the initial ease of setup. Documentation is an iterative process; you will be making hundreds of small changes. When those changes reflect in the browser in 100ms rather than 10 seconds, your productivity skyrockets.
