Jekyll vs Gatsby: Which Static Site Generator Should You Choose in 2026?

Jekyll and Gatsby both produce fast, static websites — but they come from completely different worlds. Jekyll is a mature, Ruby-based generator built for simplicity. Gatsby is a React-based framework built for power. Choosing the wrong one can mean weeks of unnecessary complexity or hitting a ceiling too early.

Here is an honest, practical comparison.

What is Jekyll?

Jekyll is a static site generator written in Ruby and officially supported by GitHub. You write content in Markdown, define layouts in Liquid templates, and Jekyll outputs a folder of plain HTML files. No JavaScript framework, no GraphQL, no build pipeline required.

It has been around since 2008 and powers hundreds of thousands of sites — including the official GitHub Pages platform.

Best for: blogs, documentation sites, portfolios, small business sites, and anyone who wants simplicity over features.

What is Gatsby?

Gatsby is a React-based static site framework that uses GraphQL as its data layer. It pulls content from anywhere — Markdown files, headless CMSs, REST APIs, databases — and compiles everything into optimised static files with automatic code splitting, image optimisation, and prefetching baked in.

Netlify acquired Gatsby in 2023. The framework is still actively maintained but is no longer the default choice for new React-based static projects, with Astro and Next.js (static export) taking significant market share.

Best for: content-heavy sites, e-commerce storefronts, sites pulling from multiple data sources, and teams already working in React.

Build speed

	Jekyll	Gatsby
Small site (< 100 pages)	< 5 seconds	15–45 seconds
Medium site (500 pages)	10–30 seconds	60–120 seconds
Large site (5,000+ pages)	2–5 minutes	5–15 minutes
Incremental builds	Yes (with flag)	Yes (experimental)

Jekyll is significantly faster to build, especially on small and medium sites. Gatsby’s build times grow steeply with content volume because of its GraphQL data layer and image processing pipeline.

Learning curve

Jekyll requires knowledge of Liquid templating and YAML front matter — both are simple and learnable in an afternoon. No JavaScript knowledge required beyond optional enhancements.

Gatsby requires React, GraphQL, and an understanding of Gatsby’s plugin ecosystem and data layer. If you already know React it is approachable. If you do not, it is a steep entry point just to publish a blog.

Winner for beginners: Jekyll by a wide margin.

Themes and design

Jekyll has a large ecosystem of free themes on GitHub, RubyGems, and marketplaces like JekyllHub. Themes are plain HTML/CSS/Liquid — easy to read, modify, and extend without tooling.

Gatsby themes are React components. They are more powerful (you can compose and shadow components) but require React knowledge to customise meaningfully. The Gatsby theme ecosystem is smaller and less active than it was in 2020–2022.

Winner for theme selection: Jekyll.

Plugins and ecosystem

Gatsby’s plugin ecosystem was once its biggest advantage — thousands of source and transformer plugins connect to every conceivable data source. That ecosystem is still there but growth has slowed since the Netlify acquisition.

Jekyll’s plugin ecosystem is smaller but covers all common needs: SEO, sitemaps, feeds, pagination, image optimisation, and syntax highlighting. The jekyll-* gem namespace has over 1,000 plugins.

Winner for integrations: Gatsby (still), though the gap has narrowed.

Hosting

Both deploy well to Netlify, Cloudflare Pages, and Vercel. Jekyll has one unique advantage: GitHub Pages hosts it natively, for free, with zero configuration. Push to a repository and your site is live.

Gatsby does not run on GitHub Pages natively (you need a GitHub Actions workflow to build and deploy).

Winner for free hosting: Jekyll.

Performance

Both generators produce static HTML, which means excellent performance out of the box. Gatsby adds automatic image optimisation via its gatsby-image / gatsby-plugin-image plugin, lazy loading, and link prefetching, which can push Lighthouse scores even higher.

For typical sites, both score 90+ on Core Web Vitals. Gatsby has a slight edge for image-heavy sites where its built-in processing pipeline matters.

Winner for out-of-the-box performance: Gatsby (marginally).

When to choose Jekyll

You want a blog, portfolio, or documentation site with minimal setup
You are not a JavaScript developer
You want to host for free on GitHub Pages
Your site has fewer than a few thousand pages
You want themes you can understand and modify without a build step

When to choose Gatsby

You are already building in React and want static output
Your content comes from multiple sources (CMS + API + Markdown)
You need advanced image optimisation built into the framework
You are building a content-heavy e-commerce or news site
Your team has React expertise and needs component composition

The bottom line

For most developers starting a blog, portfolio, or documentation site, Jekyll is the right choice. It is simpler, faster to set up, and cheaper to host. The themes are better, the GitHub Pages integration is seamless, and you will spend your time on content — not tooling.

If you are building something complex in React — pulling from a headless CMS, composing content from multiple APIs, or need advanced image processing — Gatsby earns its complexity. But in 2026, Astro is a strong contender for that use case too.

The React dependency: what it means in practice

Gatsby’s React dependency is its most consequential practical characteristic. Every Gatsby site is a React application — pages are React components, layouts are React components, even navigation and footers are React components. The benefit is access to React’s component model, hooks, and the broader npm ecosystem. The cost is a build pipeline that involves Babel, Webpack, React, GraphQL, and Gatsby’s own plugin and API layers.

For a developer fluent in React, this stack is comfortable. For a developer who wants to write Markdown and publish content, it is significant overhead. Installing Gatsby, understanding its GraphQL data layer, configuring plugins through gatsby-config.js, and debugging Webpack issues are all meaningfully more complex than the Jekyll equivalent (bundle install, write Markdown, bundle exec jekyll serve).

The complexity has a maintenance dimension too. Gatsby sites accumulate dependencies — gatsby plugins for every feature, npm packages for every utility — that require ongoing updates. A Gatsby site unattended for a year typically has dozens of outdated dependencies and potential breaking changes from Gatsby’s own version updates. A Jekyll site unattended for a year is typically still functional with a single bundle update.

GraphQL as a content layer: powerful but heavy

Gatsby’s GraphQL layer is genuinely innovative. Every data source — local files, CMS APIs, remote JSON, image metadata — is unified into a single queryable graph. A page component queries exactly the data it needs; Gatsby’s data layer fetches it during the build. The resulting pages are fast because they include only the data they need, not a full response from an API.

Jekyll’s data model is simpler and less abstract. Content comes from front matter, Markdown files, _data/ YAML files, and site.* variables — all accessed with straightforward Liquid syntax without querying. For sites with complex content relationships across many data sources, Gatsby’s unified data layer is genuinely more powerful. For sites with a standard blog structure — posts with metadata, categories, tags — Jekyll’s simpler model requires far less configuration to achieve the same result.

The GraphQL dependency also affects debugging. A Gatsby data error that traces back through a plugin’s GraphQL resolver can be difficult to diagnose without understanding Gatsby’s internal data layer architecture. A Jekyll template error that references a missing front matter field produces a clear, readable error message.

Image processing: Gatsby’s genuine strength

Gatsby’s image processing pipeline is a legitimate advantage for image-heavy sites. The gatsby-plugin-image component automatically generates multiple image sizes, converts to WebP, applies lazy loading, prevents layout shift with placeholder images, and selects the optimal size for the visitor’s viewport — all without manual configuration. The result is excellent Core Web Vitals scores on pages with many images, without the image optimisation work that Jekyll requires.

Jekyll’s image story requires more manual effort. jekyll-picture-tag provides a similar pipeline but requires configuration and is not enabled by default. Many Jekyll sites skip responsive images entirely, serving a single image size that is larger than necessary on mobile. The gap between Gatsby’s automatic image optimisation and Jekyll’s default “copy image unchanged” approach is real and significant for photographic sites.

For a photography portfolio, a recipe blog with multiple images per post, or a design showcase where image quality and loading performance are paramount, Gatsby’s image pipeline is worth the overhead. For a text-primarily blog or a technical documentation site where images are incidental, Jekyll’s image story is adequate.

Migration from Gatsby to Jekyll

The shift from Gatsby to Jekyll — often motivated by maintenance fatigue or a desire for simpler tooling — is a manageable but real migration. Your Markdown content files port directly; Jekyll and Gatsby both use Markdown with front matter, and the front matter conventions are similar enough that minimal renaming is needed. GraphQL queries in Gatsby page components have no Jekyll equivalent, so any page that fetches data from a CMS API requires reconfiguration against a Jekyll-compatible data source.

Component-based layouts in React become Liquid templates and includes. The logic is equivalent — conditional rendering, iteration, slot-based content injection — but the syntax is different. A developer comfortable with both React and Liquid can typically port a Gatsby theme to Jekyll in a week; a developer who has only used Gatsby takes longer.

The reverse migration (Jekyll to Gatsby) is similarly feasible for content; the main investment is building or adapting a Gatsby theme to match your existing design and configuring the GraphQL data layer for your content structure.

The verdict for 2026

Gatsby’s best years were 2018-2022, when it pioneered the concept of a React-based static site generator and built a large ecosystem around the idea. In 2023-2024, Astro emerged with a similar value proposition but lighter weight and the island architecture model. By 2026, developers choosing between a JavaScript-ecosystem static site generator and Jekyll are increasingly choosing Astro rather than Gatsby because Astro’s developer experience is better and its output is lighter.

For Jekyll vs Gatsby specifically: if you are building a content site, Jekyll is the simpler, lower-maintenance, lower-cost choice. If you are committed to React and need Gatsby-specific features (its image pipeline, its plugin ecosystem, GraphQL data layer), Gatsby remains the right tool for that use case — but those requirements are uncommon in purely content-driven sites.

The practical guidance: start with Jekyll unless you have a specific reason for Gatsby. You can always migrate to a React-based framework if the project’s requirements evolve to require it — and having a clean, well-structured Jekyll site as the starting point makes that migration easier than starting with a complex Gatsby configuration that you later want to simplify.
