Static Site Generators Comparison — Hugo vs Next.js vs 11ty vs Astro vs Jekyll

In this tutorial, you'll learn about Static Site Generators Comparison. We cover key concepts, practical examples, and best practices.

Static site generators (SSGs) build HTML pages from templates and content at deploy time, producing fast, secure sites that serve directly from a CDN without server-side processing.

What You'll Learn

You'll compare Hugo, Next.js, 11ty, Astro, and Jekyll across build speed, templating, ecosystem, learning curve, and ideal use cases to choose the right SSG for your project.

Why It Matters

Choosing the right SSG affects build times, developer experience, hosting flexibility, and long-term maintenance costs. JAMstack Architecture relies on SSGs for the Markup pillar. DodaTech tutorials use Hugo for its 1-second build times across 2,900+ pages.

Real-World Use

A marketing team chooses Astro for its partial hydration (ships zero JS by default), a documentation team uses Hugo for speed, and a SaaS dashboard uses Next.js for its hybrid SSG/SSR/ISR capabilities.

Feature Comparison

Hugo

Hugo is the fastest SSG, written in Go, with a single binary dependency.

# Hugo configuration (hugo.yaml)
baseURL: "https://tutorials.dodatech.com"
languageCode: "en-us"
title: "DodaTech Tutorials"
theme: "hextra"

outputs:
  home: [HTML, RSS, JSON]

markup:
  highlight:
    noClasses: false
    lineNos: true

# Build speed benchmark
time hugo --gc --minify
# Output: Building sites … 0.87s (2934 pages)

Expected output: Hugo builds nearly 3000 pages in under one second. This speed enables instant previews and rapid iteration.

Next.js

Next.js is a React-based framework with SSG, SSR, ISR, and API routes.

// next.config.js
module.exports = {
  output: "export",  // Static export mode

  images: {
    unoptimized: true,
  },

  // Static generation with dynamic routes
  async generateStaticParams() {
    const posts = await fetch("https://api.dodatech.com/posts");
    const data = await posts.json();
    return data.map((post) => ({ slug: post.slug }));
  }
};

Expected behavior: Next.js statically generates pages at build time from dynamic data sources. ISR refreshes pages periodically without a rebuild.

Astro

Astro ships zero client-side JavaScript by default and only hydrates interactive components on demand.

---
// pages/index.astro
import Layout from "../layouts/Layout.astro";
import Header from "../components/Header.astro";
import Counter from "../components/Counter.jsx"; // Interactive island
const { posts } = await Astro.glob("./posts/*.md");
---

<Layout title="DodaTech Blog">
  <Header />
  <main>
    <ul>
      {
        posts.map(post => (
          <li>
            <a href={post.url}>{post.frontmatter.title}</a>
          </li>
        ))
      }
    </ul>
    <!-- Only this component sends JavaScript to the browser -->
    <Counter client:load />
  </main>
</Layout>

Expected behavior: The static HTML contains no JavaScript. Only the <Counter/> component, marked as an island, sends JS to the browser. Total page JS: 2KB.

11ty (Eleventy)

11ty is a flexible SSG that supports multiple template languages with zero configuration.

// .eleventy.js
module.exports = function(eleventyConfig) {
  // Add a custom collection
  eleventyConfig.addCollection("tutorials", function(collectionApi) {
    return collectionApi.getFilteredByTag("tutorial").sort((a, b) => {
      return a.data.weight - b.data.weight;
    });
  });

  // Add a filter
  eleventyConfig.addFilter("readableDate", function(date) {
    return new Date(date).toLocaleDateString("en-US", {
      year: "numeric", month: "long", day: "numeric"
    });
  });

  return {
    dir: { input: "content", output: "_site" }
  };
};

Expected behavior: Eleventy processes markdown files in the content/ directory through Nunjucks templates and outputs to _site/. Custom collections and filters extend functionality.

Common Errors

1. Choosing based on popularity rather than requirements: Next.js is popular but may be overkill for a blog. Hugo or 11ty might serve better for content-heavy sites.
2. Not considering build times at scale: Next.js ISR helps but static exports with 10K+ pages require significant build infrastructure. Hugo handles 100K pages easily.
3. Assuming all SSGs support partial hydration: Only Astro, Next.js, and a few others support sending JavaScript only for interactive components. Hugo and 11ty send no JS by default.
4. Mixing template syntaxes in 11ty: 11ty supports multiple template languages. Using nested Liquid and Nunjucks syntax in the same file causes parsing errors.
5. Ignoring image optimization: Large unoptimized images destroy SSG performance. Use built-in image processing (Next.js Image, Hugo Pipes) or generate WebP at build time.
6. Over-customizing and losing SSG benefits: Heavy client-side JavaScript defeats the purpose of static generation. Keep the client bundle small.

Practice Questions

1. Which SSG is fastest for large content sites? Hugo. Written in Go with parallel processing, it builds 10K+ pages in seconds.
2. When should you choose Next.js over Hugo? When you need SSR, ISR, API routes, or a React-based component model. Hugo excels at pure static content.
3. What is Astro's island architecture? Interactive components are isolated islands in a sea of static HTML. Only the islands send JavaScript to the browser.
4. Can 11ty use data from APIs at build time? Yes, using _data/*.js files that export async functions. The API response is available in templates at build time.
5. Challenge: A project has 500 content pages, 50 interactive data visualizations, needs real-time search, and supports 5 languages. Compare which SSG fits best and justify your choice.

Mini Project

Build the same 5-page site with 3 different SSGs:

• Create the site with Hugo (Go templates, Markdown content)
• Create the same site with 11ty (Nunjucks templates, custom collections)
• Create the same site with Astro (Astro components, interactive islands)
• Measure build times for each
• Compare Lighthouse scores for each
• Compare developer experience (setup, templating, deployment)
• Write a summary of when you would choose each SSG
