Jekyll vs Next.js: A Practical Comparison for 2026
Jekyll and Next.js both produce fast websites — but they are built for very different situations. Here is how to choose between them for your next project.
Jekyll and Next.js are both capable of producing fast, statically-generated websites. But comparing them is a bit like comparing a bicycle to a car — they are built for different journeys. This guide cuts through the noise and tells you which one fits your project.
The fundamental difference
Jekyll is a static site generator. It takes your Markdown files and Liquid templates and produces plain HTML. That is all it does, and it does it extremely well.
Next.js is a full-stack React framework that happens to support static export. Its primary purpose is server-rendered and hybrid web applications. Static generation is one mode among many — not its identity.
Learning curve
Jekyll requires Markdown, YAML, and Liquid templating — none of which are programming languages in the traditional sense. A non-developer can be productive in Jekyll within a day.
Next.js requires React, JavaScript (ideally TypeScript), an understanding of server-side rendering versus static generation, and the Next.js routing model. If you do not already know React, Next.js is a significant investment.
Bottom line: Jekyll is accessible to anyone. Next.js requires a JavaScript developer.
Build output and hosting
Both can produce a folder of static HTML files ready to deploy anywhere. But the experience differs considerably.
Jekyll outputs clean HTML by default and hosts natively on GitHub Pages — push your repository and your site is live within minutes, for free.
Next.js static export (next export) works well but loses several Next.js features: API routes, middleware, image optimisation via next/image, and incremental static regeneration. If you strip out those features, you are essentially using a React-based template engine.
| Jekyll | Next.js static | |
|---|---|---|
| GitHub Pages (native) | Yes | No (requires Actions) |
| Netlify / Cloudflare | Yes | Yes |
| Vercel | Yes | Yes (first-class) |
| Output size | Very small | Larger (React bundle) |
| JS required for content | No | Yes (hydration) |
Performance
A Jekyll site ships zero JavaScript by default. The page is just HTML and CSS. This is excellent for Core Web Vitals — particularly Interaction to Next Paint (INP) and Total Blocking Time.
Next.js ships a React runtime with every page, even for fully static content. This adds 70–200kb of JavaScript that must parse and execute before the page is fully interactive. For content sites (blogs, docs, portfolios), this is overhead with no benefit.
For content-focused sites, Jekyll is faster in practice — not in theory, but in the metrics that matter for real users on real connections.
Themes and design
Jekyll has a mature theme ecosystem with hundreds of free themes on GitHub and dedicated marketplaces like JekyllHub. Themes are plain HTML, CSS, and Liquid — readable by anyone.
Next.js themes exist (Vercel has a showcase, there are paid options) but the concept of a “theme” is less central to the framework. Customisation requires React component knowledge.
When Next.js makes sense over Jekyll
- You are building a web application, not a content site
- You need API routes, authentication, or database access
- Your team is already using React across multiple projects
- You need incremental static regeneration (pages that update without a full rebuild)
- Your site pulls from a headless CMS and you need real-time preview
When Jekyll makes sense over Next.js
- Your site is primarily content: blog, documentation, portfolio, or landing pages
- You want zero runtime JavaScript on the page
- You want free hosting on GitHub Pages with no build configuration
- You are not a JavaScript developer
- You want themes you can understand and customise without a compiler
The honest answer
For a blog, documentation site, portfolio, or small business website: choose Jekyll. It is simpler, faster to build, free to host, and produces lighter pages.
For a web application with dynamic features that also needs some statically-generated pages: choose Next.js on Vercel.
The mistake people make is reaching for Next.js because it is popular, then spending weeks managing a React build pipeline to publish content that could have been a Markdown file.
