Static site generator comparison posts in 2026 mostly read like a 2018 Hugo evangelism piece updated with one Astro paragraph at the end. This is the version after running this site on Astro in production, plus shipping smaller projects on Eleventy, Hugo, and Gatsby across client work in the last two years. Five generators, real production data, no nostalgia.
Key takeaway: Astro is the modern default for content sites, Hugo wins raw build speed, Eleventy wins config-light simplicity, and Gatsby is in soft decline; pick by team and content model.
The honest 2026 picture: Astro has won the 'modern' segment definitively, Hugo has won the 'fast and language-agnostic' segment definitively, Eleventy is the right answer for the JavaScript-curious-but-config-averse niche, Gatsby is in soft decline, and Jekyll is mostly used now for GitHub Pages and legacy projects. The five-way comparison is honestly more like 'pick Astro, unless you have a specific reason', but the reasons are real, and worth knowing. The framework hub covers the broader framework decision; this post is specifically about the static-site-generator subset.
The five SSGs in 60 seconds
- Astro, multi-framework component model (React, Vue, Svelte, Solid), zero-JS by default with islands architecture, Content Layer API. The default for new content sites in 2026.
- Eleventy (11ty), JavaScript-based, configuration-light, no build-time JS shipped to the client. The right call for engineers who want JS familiarity without React or Vue overhead.
- Hugo is Go-based and avoids a Node build pipeline. It is worth testing when full-site build time dominates the release cycle. Compare it on your own content and image workload rather than assuming a universal speed multiplier.
- Jekyll, Ruby-based, native to GitHub Pages, mature template ecosystem. Mostly used for legacy projects and free GitHub Pages hosting in 2026.
- Gatsby, React-based with GraphQL data layer, in soft decline since the 2023 Netlify acquisition. Still production-stable but no longer the default for new projects.
Where each SSG actually wins
Astro: production proof on this site
Astro is a strong default for content sites needing component templates and selective interactivity. This site is a production example: 3,440 URLs across eight languages in October 2026, with a full Netlify build and deploy of about three and a half minutes. That is one site's configuration, not a portable framework benchmark. The choice depends on content sources, image work, deployment frequency, and team skills.
- Wins on: modern content sites at any scale, programmatic SEO, multi-framework flexibility, the ecosystem that has all the modern integrations.
- Falls short on: teams that do not want a JavaScript build toolchain, and full rebuilds that exceed the project's deployment budget. Measure the actual site before attributing a slow build to Astro itself.
Eleventy: JavaScript without the framework overhead
Eleventy is the SSG for engineers who want JavaScript-based templating without committing to React, Vue, or any specific component model. The configuration is genuinely minimal, the build pipeline is simple, and the output is clean HTML by default. Right call for blog-shaped sites, documentation, and small marketing sites where 'I just want HTML' is the brief and Astro's component model feels like overkill.
- Wins on: JavaScript familiarity without framework overhead, simple blog and documentation sites, configuration-light approach.
- Falls short on: complex interactive components (you bring your own approach), large ecosystems of pre-built integrations versus Astro.
Hugo: build speed when it actually matters
Hugo is worth testing when build time is the bottleneck. An Astro-to-Hugo comparison is only meaningful with the same content, image transformations, runner, cache state, and output requirements. A generic 5,000-page timing cannot establish your project's result.
- Wins on: build speed at scale, language-agnostic teams, sites past 20K pages where build time is a real cost.
- Falls short on: modern component model (Go templates feel dated for engineers used to JSX), small-team adoption (fewer engineers know Go templates than know JSX).
Jekyll: GitHub Pages and legacy maintenance
Jekyll is mostly used in 2026 for two reasons: GitHub Pages native support (free hosting if your site is Jekyll-shaped), and legacy maintenance of sites originally built when Jekyll was the default. For a new project in 2026, the only Jekyll-pick is 'I want free GitHub Pages hosting'. Astro on Cloudflare Pages or Netlify free tier is usually the modern equivalent.
- Wins on: free GitHub Pages hosting, legacy site maintenance.
- Falls short on: most modern needs, slower builds than Hugo, more dated tooling than Astro, smaller ecosystem than either.
Gatsby: production-stable, soft decline
Gatsby is in slow decline since the Netlify acquisition in 2023. The framework is stable and production-running sites keep running, but new projects are not picking Gatsby in meaningful numbers. The GraphQL data layer that was Gatsby's differentiator in 2018 is now mostly considered overkill for content sites, Astro's Content Layer API and Next.js's data fetching cover the same ground without the GraphQL overhead. Right call only when you have a Gatsby site already and migrating off is not worth it.
- Wins on: existing Gatsby sites where the migration cost is not worth it.
- Falls short on: new projects (the community has moved), feature velocity (development pace has slowed since the acquisition).
The decision tree, pick by build size and team shape
Modern content site under 10K pages, JavaScript-comfortable team
Astro. The default. Use the Content Layer API for any content source, Server Islands for occasional dynamic content, and the integrations ecosystem for everything else. This is the 80% case in 2026.
Site past 20K pages with daily deploys
Benchmark Hugo if full rebuilds on Astro are slowing daily releases. Build an equivalent Hugo version of your own content before predicting the speed difference. At very large page counts, also consider incremental regeneration instead of full rebuilds; Deluxe Astrology serves 91,000+ pages on Next.js that way.
Blog or documentation site, configuration-averse
Eleventy. JavaScript-based, minimal configuration, clean HTML output. Right when 'I just want HTML' is the brief.
Free GitHub Pages hosting required
Jekyll. The only category where it is still the default in 2026, GitHub Pages native support means zero hosting infrastructure to maintain.
Existing Gatsby site
Stay on Gatsby unless the migration solves a concrete problem. Estimate effort from your content model, routes, integrations, and design system; a generic four-to-eight-week figure is not reliable for every production site.
How to benchmark build time for your site
The earlier numbers in this section were illustrative ranges for a hypothetical 5,000-page site, not measurements of identical implementations. To make a real platform decision, build the same representative content and images on the same CI runner, with both a cold cache and a warm cache.
- Record total build time, memory peak, image-processing time, output size, and the number of pages regenerated after one edit. Hugo's fast content pipeline may help, but image work and deployment can still dominate.
- Eleventy's result depends on templates, plugins, and how content is loaded. Include the actual plugin stack in the test.
- Astro's component build, content loading, and image pipeline all affect full rebuilds. Measure the production build rather than extrapolating from a starter project.
- Jekyll's result depends on Ruby plugins, collections, and incremental-build settings. GitHub Pages compatibility may outweigh a build-time difference for a small site.
- Gatsby can spend substantial time in its data and image pipeline. Benchmark the existing project before scheduling a migration solely to improve CI.
At tens of thousands of pages, test the content update that happens most often, not just a clean full build. A slower full build may be acceptable with caching or selective publishing; a fast local build may still deploy slowly when the output is very large.
For implementation details, use the Astro documentation and each generator's own build guidance. Keep the benchmark script and runner settings with the published comparison so another team can reproduce the result.
FAQ
Astro is often the better fit for a JavaScript team building a component-driven content site. Hugo is worth testing when build time, a Go-oriented team, or a simpler content pipeline drives the decision. Compare both using the same representative workload.
Astro is often the better fit for a JavaScript team building a component-driven content site. Hugo is worth testing when build time, a Go-oriented team, or a simpler content pipeline drives the decision. The previous five-to-ten-times speed claim was not an equivalent-site measurement.
Should I migrate from Gatsby to Astro?
Only if the Gatsby site is causing real problems: slow builds, data-layer complexity, or dependency drift that the team cannot maintain. Estimate the migration against that cost. A production Gatsby site that works well may be better left in place.
Why is Hugo so much faster than Astro?
Hugo is written in Go, compiles to a single binary, and uses Go's templating engine which is optimised for static text generation. Astro is JavaScript-based, runs through Node, and uses the React/Vue/Svelte renderers as needed. The fundamental architecture difference is real and not closing, Astro will not catch Hugo on build speed because the languages are different. The Astro answer is 'good enough for most sites'; Hugo is 'meaningfully faster when it matters'.
Is Eleventy still relevant in 2026?
Yes for engineers who specifically want a configuration-light JavaScript SSG without Astro's component model. Eleventy is more 'just give me HTML' than Astro is, and that simplicity is genuinely valued by some teams. For most modern content sites, Astro is the more powerful default; for blog-shaped sites where simplicity is the explicit goal, Eleventy still wins.
Can I use Jekyll outside GitHub Pages?
Yes. Jekyll runs on any Ruby-capable host. GitHub Pages is its easiest path; Astro on Cloudflare Pages or Netlify is another option, but check the current host plan and build economics before assuming the same free capacity.
