Alright, let’s get the awkward “which static site generator is best” conversation out of the way. It’s a bit like picking a favorite tool: the right one depends entirely on the job you’re doing and how you like to work. I’ve built sites with all of these, and I can tell you that while they all ultimately produce HTML, CSS, and JS, their philosophies and day-to-day developer experiences are wildly different. Let’s break it down.

The Core Philosophy: Batteries Included vs. à la Carte

Hugo’s design is opinionated. It comes with a full set of tools built-in and optimized to work together. Think of it like a master chef’s kitchen where every pot, pan, and knife is perfectly balanced and hanging right where it should be. Jekyll, Gatsby, and Astro, on the other hand, lean heavily into the Node.js ecosystem. Your kitchen is mostly empty, and you install every appliance (plugins) yourself. This is powerful, but it also means you spend a lot of time reading manuals for your new bread machine instead of, you know, baking bread.

Hugo’s “batteries included” approach means things like image processing, Sass compilation, and data transformations are handled internally by Go code. This is why it’s so blisteringly fast. There’s no plumbing between a dozen different Node modules. It’s one integrated system.

The Speed Benchmark: It’s Not Even a Contest

Let’s be direct: Hugo is in a different league when it comes to build times. We’re talking orders of magnitude faster. A site that takes Jekyll 30 seconds to build will take Hugo less than a second. For Gatsby, a site with a few thousand pages can take minutes. Hugo handles it in seconds.

Why? It’s written in Go, a compiled language designed for concurrency. It’s not waiting around for a single-threaded JavaScript runtime to do everything sequentially. It uses all your CPU cores to build pages simultaneously. This speed isn’t just a nice-to-have; it fundamentally changes your workflow. You can hit save and see the result instantly. It makes experimentation and iteration a joy instead of a chore.

Data Handling: Flexibility Without the Bloat

All these generators can handle data, but Hugo’s integration of Go templates gives you a startling amount of power without needing a separate data-fetching runtime.

Take this example. You have a JSON file of products, data/products.json. In Hugo, querying and transforming that data is a native operation right in your template:

{{/* This is all happening at build time, not runtime */}}
{{ $featuredProducts := where (site.Data.products) "featured" true }}
{{ range first 3 $featuredProducts }}
  <div class="product">
    <h3>{{ .name }}</h3>
    <img src="{{ .image }}" alt="{{ .name }}">
  </div>
{{ end }}

In Gatsby, you’d need to source the node, which involves configuring gatsby-source-filesystem and gatsby-transformer-json in your gatsby-config.js, then writing a GraphQL query in your component. It’s powerful, but it’s a lot more ceremony for the same result. Astro and Eleventy sit somewhere in the middle, offering more flexibility than Hugo’s built-in way but generally with less overhead than Gatsby’s GraphQL layer.

The Ecosystem: Plugins vs. Built-in Features

This is Hugo’s trade-off. Jekyll, Gatsby, and Eleventy have massive plugin ecosystems. Need to generate a sitemap? There’s a plugin for that. Need to inject analytics? There’s a plugin.

Hugo’s stance is, “Why would you need a plugin for that? It’s built-in.” For core website functionality, this is almost always true. Sitemap? Built-in. RSS feeds? Built-in. Image processing? Built-in. Pagination? Built-in.

The downside is that if you need something truly esoteric—say, sourcing data from a proprietary API that no one has ever heard of—you might find more pre-built solutions (plugins) for the JavaScript-based frameworks. For Hugo, you’d likely drop down to writing a custom data function or using its built-in HTTP get capability, which is more work but often results in a more robust, faster solution.

The Developer Experience: Go Templates and Your Sanity

Hugo uses Go templates. They are… an acquired taste. They are not a full programming language like JavaScript, which can be frustrating at first. You can’t arbitrarily manipulate data anywhere you want. You have to think in the way the templates are designed: pipes and functions.

{{/* This is the Hugo way: piping data through functions */}}
{{ $image := resources.Get "images/party.jpg" }}
{{ $small := $image.Resize "500x" }}
{{ $small = $small | images.Filter (images.GaussianBlur 6) }}
<img src="{{ $small.RelPermalink }}" alt="Blurry party">

The JavaScript frameworks let you use, well, JavaScript. If you can write a function in JS, you can use it in your template. This is Astro and Eleventy’s huge win. You’re never fighting the templating language. Gatsby, of course, is all-in on React, for better or worse.

So, who wins? If you need the absolute fastest build times and value a robust, integrated toolset, Hugo is your champion. If your site is fundamentally a React application that just happens to be pre-rendered, Gatsby (or better yet, Astro) is your pick. If you want the flexibility of the Node ecosystem with a simpler, less-opinionated approach than Gatsby, Eleventy is fantastic. And Jekyll? It’s the old reliable that’s still perfectly fine, but it feels its age compared to the modern alternatives. Choose your weapon.
