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.
