Best Static Site Generators in 2026: Astro to Hugo

For most new marketing sites and blogs in 2026, Astro is the default choice: content-first, zero JavaScript unless you opt in, and adapters for every host. Pick Next.js static export when your team is already invested in React and may need server features later, and Hugo when raw build speed on thousands of pages matters more than a JavaScript ecosystem. Jekyll remains fine for small GitHub Pages sites, and Gatsby should not be used for anything new.

What changed in static site generators since the Jekyll vs Hugo vs Gatsby era

The original three-way comparison assumed a trade-off: fast builds with a rigid template language (Hugo, Jekyll), or a modern component model paid for with slow builds and heavy client-side JavaScript (Gatsby). That trade-off no longer holds.

Three things moved the market:

• Islands architecture. Astro popularized rendering a page as static HTML and hydrating only the components that need JavaScript. A marketing page ships zero JS by default; the newsletter form or pricing toggle hydrates on its own. This removed Gatsby's main cost without giving up React, Vue, Svelte or Solid components.
• Vite as the shared toolchain. Astro, VitePress, Docusaurus (as of its recent major versions) and most of the Vue and Svelte world build on Vite. Dev server startup dropped from tens of seconds to well under a second, and plugins carry across tools. See Vite vs Webpack vs Parcel for the build-tool side of this shift.
• Full-stack frameworks that also export static. Next.js, Nuxt and SvelteKit all support prerendering everything to plain files. A team can start static and turn on server rendering for one route later without switching frameworks.

The result is that "static site generator" now describes an output mode more than a category of tool. The question is no longer "which SSG" but "which content model and which hydration strategy," with hosting on a CDN as the constant. The Jamstack architecture post covers the hosting and API side in more depth.

Build numbers are orders of magnitude. Measure with your own content before deciding; image processing and data fetching dominate build time far more than the generator's template engine does.

Astro: the content-first default

Astro renders .astro components to HTML at build time and strips all JavaScript unless a component carries a client:load, client:idle or client:visible directive. You can drop in React, Vue, Svelte, Solid or Preact components side by side, which makes it the least risky choice when a team has mixed front-end skills.

Content collections give Markdown and MDX a typed schema:

// src/content.config.ts
import { defineCollection, z } from 'astro:content';
import { glob } from 'astro/loaders';

const blog = defineCollection({
  loader: glob({ pattern: '**/*.md', base: './src/content/blog' }),
  schema: z.object({
    title: z.string(),
    date: z.date(),
    tags: z.array(z.string()).default([]),
  }),
});

export const collections = { blog };

A missing field fails the build instead of producing a blank page. Loaders also pull from a headless CMS or an API using the same interface, so switching from local Markdown to a CMS does not touch your templates. See headless vs traditional CMS for how to make that call.

Where Astro falls short: very large sites (tens of thousands of pages) build slower than Hugo, and if you need a real application shell with client-side routing everywhere, a full framework fits better. Astro also supports server rendering through adapters, so the escape hatch exists.

Next.js static export: for React teams that may need more later

Next.js with output: 'export' in next.config writes plain HTML, CSS and JS into an output folder that any CDN can serve.

The important part is what static export turns off: middleware, API routes, server actions, Incremental Static Regeneration, on-demand revalidation, image optimization (set images.unoptimized: true), and built-in i18n routing. Every dynamic route needs generateStaticParams. If you rely on any of those, you are no longer building a static site and should host on a Node or edge runtime instead.

Two practical rules from running Next.js export at a few hundred pages:

• Memoize data loaders. generateStaticParams, generateMetadata and the page component all call your content loader for each page. Without a cache, a few hundred pages can trigger tens of thousands of file reads and turn a 30-second build into several minutes.
• Enable trailingSlash: true and link with it. Static hosts serve /about/index.html; a link to /about produces a redirect that crawlers index instead of the page. This matters for Core Web Vitals and technical SEO.

Choose Next.js export when you share components with a React application, when your team's muscle memory is React, or when you want a credible path to server rendering. Choose Astro when the site is content and the React dependency buys you nothing.

Hugo and Eleventy: no-JavaScript builds that scale

Hugo is a single Go binary. Install it, run hugo, and thousands of Markdown pages become HTML in seconds. There is no node_modules, so CI is a download and a single command. Multilingual support is built into the content model (one directory tree per language, or a language suffix per file), taxonomies are native, and image processing runs in templates. Go templates are the main learning cost: terse, unfamiliar to JavaScript developers, and unpleasant to debug. Hugo is the best choice when content volume is large, the team does not want a JavaScript toolchain, or you need multilingual routing with no plugins.

Eleventy (11ty) takes the opposite stance: minimal core, JavaScript configuration, and your choice of template language (Nunjucks, Liquid, WebC, plain JS). It has no opinion about client-side JavaScript, which means the default output is zero JS. Data can come from anywhere a JavaScript function can reach. The image plugin is one of the best in the category. Eleventy is the right pick when you want Hugo's output philosophy with a JavaScript ecosystem and full control over every step. The trade-off: no built-in i18n routing or typed content schema.

A minimal Eleventy build:

npm install @11ty/eleventy
npx @11ty/eleventy --serve

Jekyll and Gatsby: what to do with them in 2026

Jekyll still ships, still runs GitHub Pages, and still works for a personal site or a small project page with a handful of Markdown files. Its problems are practical: Ruby toolchain drift across machines, a plugin allowlist on GitHub Pages, slow builds with many plugins, and a much smaller pool of active themes. Pick Jekyll only when GitHub Pages' zero-configuration hosting is the whole point. Otherwise start on Eleventy, which accepts Liquid templates and Jekyll-style front matter and makes the move gentle.

Gatsby was the first tool to combine React, a GraphQL data layer and image optimization in one package, and it deserved its popularity around 2019. Then two things happened. React moved to Server Components and a "less client JavaScript" model that Gatsby's full-hydration architecture could not adopt without a rewrite. And after Netlify acquired Gatsby Inc., the framework moved to a maintenance cadence: fixes ship, but the source-plugin ecosystem, the cloud build product and the documentation stopped keeping up. A team choosing Gatsby today inherits a webpack-based build, a GraphQL layer few people want to maintain, and long build times without the incremental builds that only the discontinued Gatsby Cloud handled well.

Docusaurus and VitePress: documentation sites

Documentation has requirements the general-purpose tools handle poorly: versioned docs, sidebars generated from the file tree, search, API reference pages, and translated docs that track versions.

Docusaurus covers all of that out of the box. It is React-based, supports MDX, ships versioning and i18n as core features, and has plugins for OpenAPI references and search. The cost is a heavier build, full React hydration, and more configuration.

VitePress is smaller and faster. It is Vue-based, builds on Vite, and produces a clean docs site with sidebar, search and dark mode from a single config file. It does not do versioning natively, so it suits library documentation, internal engineering docs and single-version products.

Astro Starlight is the third option: a docs theme on top of Astro with i18n, sidebars and search. If the rest of your sites are Astro, Starlight avoids running a second framework.

Migrating from Jekyll or Gatsby

Content in Markdown with front matter is portable. The work is in URLs, images and templates.

From Jekyll:

1. Export the _posts and _pages folders as-is. Front matter keys (title, date, layout, permalink) map directly to Astro content collections or Eleventy data.
2. Rewrite Liquid templates. Eleventy accepts Liquid natively, so the theme can move with minimal changes. Astro requires rewriting layouts in .astro, which is usually a day or two for a typical blog.
3. Preserve permalinks. Jekyll's default /:year/:month/:day/:title/ pattern must be reproduced or redirected. Generate a redirect map (_redirects on Cloudflare Pages or Netlify) from the old sitemap before switching DNS.
4. Move image processing out of Ruby plugins into the generator's image pipeline.

From Gatsby:

1. Remove the GraphQL layer first. Gatsby's useStaticQuery calls become direct imports or content-collection queries. This is most of the work.
2. React components port to Next.js unchanged and to Astro with a client:* directive where they need to hydrate; most will not need one.
3. Replace gatsby-plugin-image with next/image (with unoptimized and a preprocessing step) or Astro's <Image>.
4. Replace gatsby-source-* plugins with fetch calls in a loader. Contentful, Sanity and similar CMSs all have plain SDKs.
5. Audit gatsby-browser.js and gatsby-ssr.js for global wrappers; they become a root layout.

In both cases, diff the generated HTML for a sample of pages and crawl the new build for 404s before cutover. Keep redirects from the old sitemap for at least a few months.

Decision checklist by project type

Use the first matching line.

• Marketing site with a CMS and some interactive components. Astro. Use islands for the interactive parts and a CMS loader for content. Next.js export if the marketing site shares a component library with a React app.
• Product or API documentation, versioned. Docusaurus. Single version, Vue-friendly team or internal docs: VitePress. Already on Astro: Starlight.
• Blog or editorial site with hundreds of posts. Astro or Eleventy. Above roughly ten thousand pages, or with no JavaScript toolchain allowed in CI: Hugo.
• E-commerce storefront. A static generator handles catalog and landing pages; cart, checkout and account need client-side code or a server. Next.js (usually not in export mode) or Astro with server-rendered routes. Purely static is only viable with a headless commerce API and client-side cart.
• Multilingual site. Astro (built-in i18n routing and fallbacks) or Hugo (mature per-language content trees). Avoid Next.js export unless you are prepared to build locale routing yourself; the framework's i18n does not work in export mode. The i18n and localization post covers the content-side decisions.
• Small personal or project site on GitHub Pages with no build step. Jekyll is still acceptable. Anything with growth plans: Eleventy.
• Existing Gatsby site. Plan the migration; do not add features.

Recommendation

Default to Astro for new content sites. It ships the least JavaScript, its content collections catch errors at build time, and it lets you use whichever component framework your team already knows. Move to Next.js static export only when React is already the company standard and you expect the site to grow application features. Pick Hugo for large or multilingual content sets where a Go binary in CI is a feature rather than a constraint. Use Docusaurus or VitePress for documentation instead of bending a general-purpose tool. Keep Jekyll for the small GitHub Pages case, and treat Gatsby as a migration source, not a target. At Arvucore we usually recommend Astro or Next.js export for client marketing sites, and we run this site on Next.js static export for exactly the React-sharing reason above.
