Sweet. Sticky. Spreadable. All words that describe that jar of jam in your refrigerator. But they’re also fitting descriptors for the popular “JAMstack” craze that’s spreading across the web development world.
In this article, we’ll share some of the sweetest selections for static site generators on our radar in 2021 – and why we think they’ll be sticky well into the future.
But first… what exactly is this JAMstack stuff? And why is it gaining such popularity?
Together, this “stack” of resources is used to generate high-performing static sites that are more secure and scalable – and don’t depend on a server to dynamically render everything. This means blazing-fast load times for web pages.
OK, back to the “JAM.” Not to spread it on too thick, but here’s some additional context for each component (feel free to read more here):
Markup: This is where the magic happens. We all recognize HTML as the foundational language of the web, and whether that’s hand-coded or compiled, it’s the first thing a website visitor is served. In the JAMstack, markup is served statically, meaning it’s not being dynamically rendered at the server level. These can be generated from source files (such as markdown) using what’s called a “static site generator.”
Benefits of using JAMstack
A JAMstack architecture can bring all sorts of benefits to websites and workflows. These include:
Higher speed and scalability
As mentioned, JAMstack sites cache everything in a CDN, which removes the need to generate page views from a server at the time of request. Instead, pages are made readily available on the CDN and pushed closer to the user – ready to serve at incredible speeds and scale with increased traffic loads.
No servers? No database vulnerabilities! Serving pages and assets as pre-generated files allows for read-only hosting, which reduces attack vectors even further.
Hosting of static files is cheap – and in some cases, even free. And since there are no servers, you’re (typically) not on the hook for any server-related fees.
Better developer experience and maintainability
JAMstack sites can be created with a wide variety of tools and given their static nature, they don’t require an army of experts to maintain. As a result, developers can really focus on what they love to do: build.
Which JAMstack site generators are the best?
The JAMstack is getting jam-packed with static site generators. While the cream generally rises to the top, our team reviewed a slew of solutions that are building steam in 2021. We also paid close attention to how each platform integrates with CMS, both hybrid and headless.
Here are the top seven contenders:
There’s no doubt that Gatsby’s on a roll, becoming one of the most popular static site generators on the market. In just a few short years, the platform has amassed thousands of users worldwide – and closed on $28 million in Series B funding in 2020.
Gatsby brings some great plugins, themes, and starters to their ecosystem, giving users more than one way to build a site. Their browsable library offers a rich landscape of CSS, UI, analytics, eCommerce, search, and media capabilities – all under one roof.
As far as CMSes are concerned, Gatsby is a winner with its array of hybrid headless and API-first content management system integrations. This includes leading CMS platforms like Contentful, WordPress, Strapi, Drupal, Shopify, Ghost, Agility, Contentstack, and more.
Gatsby.js v3.0 was unveiled in early 2021 at GatsbyConf (their global users’ event), which offers some amazing new features such as incremental builds, intelligent caching in the Gatsby Cloud, higher Lighthouse scores, and the all-new Gatsby Hosting – which includes a secure global CDN from Fastly.
Perhaps one of the biggest advantages of Gatsby is their active community, which is a testament to their meteoric rise. Along with providing a wealth of user resources, Gatsby offers professional services and world-class support, which illustrates their commitment to the customer experience up and down the market.

Hugo is another popular static HTML and CSS website generator written in Go. It’s optimized for speed, ease of use, and overall configurability – and as their website claims, it makes building websites “fun again.”
Hugo has a solid reputation for extremely fast builds. In fact, this video on YouTube shows Hugo generating a site with 5,000 posts in less than 7 seconds. Pretty impressive.
Judging by its GitHub stars, Hugo has a fairly robust community of users. That means lots of interaction and resources – and a good sign that innovation is happening across repos. Hugo also offers 300+ themes to take the hassle out of building a site from scratch.

Started by GitHub founder Tom Preston-Werner, Jekyll is a simple, blog-aware, static site generator that’s perfect for personal, project, or organizational sites. Jekyll has been around since 2008 – and is one of the most widely used static site generators with over 42 thousand stars on GitHub.
One of the things that makes Jekyll so attractive is that you can take practically any website and turn it into a Jekyll website by using its simple templating library. Jekyll also powers GitHub Pages, which you can use to host sites right from your GitHub repositories. Like Gatsby and Hugo, Jekyll offers some great theme options, as well as hosting and CMS solutions like CloudCannon, Forestry, and more.
At its core, Jekyll does what you tell it to do. It doesn’t try to “outsmart” users by making bold assumptions, nor does it burden them with needless complexity and configuration. Put simply, Jekyll gets out of your way and allows you to concentrate on what truly matters: your content. This is one of its biggest advantages.
Wading into the technical weeds: it’s worth noting that Jekyll is built with Ruby, so you’ll need a Ruby environment on your computer for the Liquid templating language to process templates. You’ll also need to get familiar with Gems and other terminology – but you can always tap the community for helpful videos, resources or to resolve a bug.

One other big advantage of Next.js is that it’s primed for SEO. Again, with server-side rendering, it’s easier to customize meta descriptions that improve how Google and other search engines crawl and index your pages. Next.js also has built-in handling of SEO at the page level.
Like the other site generators in this review, there are plenty of theme options out there for Next.js, although primarily from third-party sources. There are some great collections of paid and free options, many with Bootstrap and responsive templates out of the box.
One of the reasons why developers still flock to this environment is that it offers a lot of freedom to build websites and web apps from scratch – something many platforms place limits on. Next.js also has an active dev community that continues to support and enhance the horizon of the technology and the underlying Node.js framework.

Publii is a little different from the other players on this list. Not only is it a static site CMS, but the generator itself is downloaded and utilized as a desktop application. Available for both Windows and Mac, Publii is installed locally on your system rather than on the server-side – allowing you to create and update your website or web app even if you’re offline.
Publii is also very “beginner-friendly.” Users from all skill levels can get rolling with Publii in no time at all – and scale more complex builds in multiple directions. This makes it attractive to a wider audience of developers who want to focus on building.
There are some great advantages to Publii. First, it’s fast! Most of the bloat was cut from what other website builders offer, so page load times are significantly shorter than the same post built on a different platform.
Publii also makes it easy to manage SEO, providing built-in tools that let you control the page title, slug, and meta information across your web pages. You can also tag posts to be indexed (or not).
Whether you start a website from scratch or download a theme, you may want to write your own custom HTML and CSS. Publii has a separate container for custom CSS, so you don’t have to scroll through an entire document to make edits. This can also prevent the removal of any CSS that might break how your site displays.
Publii also released their latest update, Publii v0.38, in March of 2021, with a host of new features. This includes the ability to minimize the sync popup, new options to hide menu items, WebP image support, and even more flexible SEO options.
It might be easy to confuse “Nuxt.js” with “Next.js,” but there’s a big difference between these two frameworks: while Next is built on React.js, Nuxt is built on Vue.js.
Next.js is certainly the more popular of the two (36K Github stars versus 19K), but we wanted to represent a Vue.js option that really does some slick and highly intuitive things.
Nuxt.js is a higher-level modular framework that helps you create production-ready Vue applications. It lets developers build from scratch by eliminating the need for excessive configurations on both the server and client side, allowing you to set up your project with intelligent defaults based on well-researched best practices.
Vue doesn’t have a standard folder structure out-of-the-box. But Nuxt brings order to the chaos by setting up folders like a page directory for an application’s routes and default conventions – which are all configurable. This gives you a great project structure.
Vue applications aren’t inherently SEO-friendly. You could pre-render your pages on the server as a solution, but it might be tricky to set up your own. Nuxt is preconfigured to generate your application on the server, along with powering your routes to make it easy to add SEO-related tags.
There are many other advantages to this handy platform, but it still comes down to UI rendering that abstracts away the server. You can statically render your Vue app and benefit from a powerful routing system and other features that make development faster and easier.

7. Eleventy (or 11ty)
We’re not entirely sure which is the preferred spelling, but we’ll stick with Eleventy for simplicity’s sake. Regardless, it’s a platform worth evaluating because of its simplicity – and its democratized philosophy around decoupling content.
With Eleventy, you don’t need a blank slate to get started. You can work from a set of pre-rendered templates or migrate existing content piecemeal. You can also use an existing project directory structure to help streamline any conversions.

JAMstack and DXP: the future of digital experiences?
While digital experience platforms (DXP) have been gaining ground, they’ve been hyper-focused on consolidating around a new stack of essentials. We’ve seen big acquisitions by major players over the last few years, racing to weave together content management (CMS), testing and analytics, marketing automation, CRM, and personalization.
Then, Covid-19 happened – and the pandemic ignited digital transformation across the globe. Now, leading brands face significant challenges that require more resources to meet their growing digital demands.
DXPs will have to wrestle with this challenge as speed and performance become more critical from a customer experience perspective. Will they be able to scale to meet unprecedented traffic? As they add new technologies, how will they cope with slower-moving architectures that stymie developer velocity?
This is where the JAMstack offers some huge opportunities for DXP. While the two have been separated by the classic gulf between marketing and IT, JAMstack players like Gatsby have made it their mission to bring these worlds together in a more meaningful way.
Even though most DXPs aren’t using JAMstack, they may want to take a hard look at the advantages: sub-second page loading, personalized content, modern front-end development tools, faster development cycles, unmatched scalability and security, and even greater control for DevOps teams to handle infrastructure issues.
Headless CMS has already carved a niche in the JAMstack ecosystem – and given the API capabilities of many DXPs, they might already be positioning themselves for a similar leap. In the meantime, the JAMstack offers some great opportunities with proven solutions – the kind that are sure to be sweet, sticky, and spreadable for some time to come.
