Astro and Jekyll both turn Markdown files and templates into static HTML pages. They get there in different ways. Jekyll is a Ruby program, installed as a gem, that builds pages from Liquid templates. Astro is a JavaScript framework that runs on Node.js and builds pages from components. That difference decides who can maintain the site, how it’s hosted and how much interactivity you can add without extra work.
We build Astro sites through our Astro web development service, and this site runs on Astro, so weigh that. This comparison also says plainly where Jekyll is the better tool. Every fact below was checked against each project’s own documentation in October 2026.
Short answer: choose Jekyll for a blog or documentation site on GitHub Pages that only needs what Jekyll ships with, or for an existing Jekyll site that works. Choose Astro when the site needs interactive components, pages rendered on demand, or a team that already works in JavaScript.
Astro and Jekyll at a Glance
As of October 2026, from each project’s documentation and repository:

GitHub Pages: Jekyll’s Home Ground
Jekyll’s best-known advantage is GitHub Pages. Push a Jekyll site to a repository and GitHub can build and host it, with no build pipeline to set up.
There’s a catch that most comparisons leave out. GitHub Pages doesn’t build with the current Jekyll. Its published dependency list shows Jekyll 3.10.0 and Liquid 4.0.4 (source), while Jekyll itself is on version 4.4.1. GitHub Pages also only runs a fixed set of plugins, such as jekyll-feed, jekyll-sitemap and jekyll-seo-tag. GitHub’s documentation is direct about the rest: GitHub Pages “cannot build sites using unsupported plugins” (source). To use Jekyll 4 or another plugin, you build the site yourself and publish the output, usually with a GitHub Actions workflow.
Astro deploys to GitHub Pages the same way. Its documentation calls the official withastro/action “the recommended way to deploy to GitHub Pages” (source). You add a workflow file, set site and base in the Astro config and pick GitHub Actions as the Pages source.
So the zero-setup advantage is real, but only while the site stays within what GitHub Pages builds natively. Once you need a workflow anyway, both tools are deployed the same way.
Templates: Liquid vs Components
Jekyll uses Liquid. Pages are built from layouts and includes (reusable template pieces), with data from front matter and from YAML, JSON or CSV files. Liquid is readable and well documented, and it’s the same language Shopify themes use, so it’s familiar to some front-end developers.
Astro builds pages from components. An .astro file looks like HTML with a block of JavaScript at the top, and each component takes props and can be reused anywhere. You can also use components written for React, Vue, Svelte, Solid or Preact on the same page. For a team that already builds in JavaScript, that means less to learn and access to the npm ecosystem. Our post on what the Astro framework is explains the model in more detail.
In practice, this decides who can maintain the site. A Jekyll site needs someone comfortable with Liquid and the Ruby toolchain. An Astro site needs someone comfortable with JavaScript and Node.js tooling.
Blog Features Out of the Box
Jekyll was built for blogs, and it shows. Posts, tags, categories and permalink patterns are built in, and official plugins add an RSS feed, a sitemap and SEO tags.
Astro starts from a blank project. Markdown content goes into content collections, which check each post’s front matter against a schema you define, so a missing date or a misspelt field fails the build instead of shipping. Astro’s own Jekyll migration guide notes that tags and categories are built into Jekyll but not into a minimal Astro project (source). You build them, or start from a blog theme that includes them.
For a plain blog, Jekyll needs less setup. For a site where the blog is one part of a larger marketing site, Astro’s components and schemas tend to pay off.
Interactive Features
Jekyll outputs HTML and leaves the browser side to you. Adding a menu, a filter or a form handler means adding script files and including them in your layouts. That works for a few pieces. As they multiply, you’re wiring each one up by hand, without a component model that ties markup and behaviour together.
Astro components render to HTML and send no JavaScript to the browser unless you ask. When a component does need to run in the browser, you add a client directive: client:load hydrates it as soon as the page loads, client:visible waits until it scrolls into view. Astro calls these islands, and our guide to Astro islands architecture shows how they work. The rest of the page stays static HTML.
For a site with a contact form and a mobile menu, both approaches work. For a site with a pricing calculator, filters and search, Astro’s islands are less work to build and maintain.
Static Only, or Static Plus Server
Jekyll produces static files, and that’s all it does. Anything that needs a server, such as form handling, personalised content or an API, lives in a separate service.
Astro prerenders every page by default, the same as Jekyll. With a server adapter installed, you can mark individual routes to render on demand by adding export const prerender = false. That lets one project hold the static marketing pages, a form endpoint and a page that changes per request. This site is an example: designodin.com runs on Astro 6 in server output mode on Cloudflare, with content pages and API routes in the same codebase. Our guide to static vs dynamic Astro sites covers when each mode fits.
If the site will only ever be content, this doesn’t matter. If you expect to add forms, logged-in pages or integrations later, it’s worth knowing whether the framework can grow with you.
Build Speed vs Page Speed
Both tools rebuild the site from your files, and both get slower as page counts grow. Jekyll offers incremental regeneration to rebuild only what changed, but its documentation says it “is still an experimental feature” (source). Astro builds run through Node.js and Vite and process components, styles and images along the way. For a business site or blog with a few hundred pages, neither is likely to be a problem.
Build speed and page speed are separate things. Both tools produce static HTML, so a visitor loads a finished file either way. How fast that page is depends on how it was built: image sizes, how much JavaScript ships, fonts and hosting. Astro makes the light version the default, with no JavaScript unless a component asks for it and <Image /> producing WebP files. A careful Jekyll site can be just as fast. Our Astro performance benchmarks post covers what affects the numbers.
Content Editing
Neither Jekyll nor Astro has a content editor. Content lives in Markdown files in a Git repository, which works well for developers and less well for a marketing team that wants to publish without opening a code editor.
The fix is the same for both: connect a Git-based CMS such as Decap or TinaCMS that edits the Markdown files through a web interface, or a headless CMS that stores content and serves it over an API. Our guide to Astro CMS options for non-developers walks through them. If a no-code editing experience matters most, also look at Astro vs WordPress and when to choose Astro over WordPress.
Dependencies and Upkeep
Jekyll needs Ruby, RubyGems and build tools on any machine that builds the site, and its plugins are Ruby gems, usually managed with Bundler. Ruby versions and gems need occasional updates. On GitHub Pages, the versions are chosen for you, which is simpler but ties you to Jekyll 3.10.0.
Astro is a Node.js project with npm dependencies: Astro itself, its integrations and any libraries you add. Those packages need updates over time, and major Astro versions sometimes need migration work. That’s the normal cost of a JavaScript project.
Either way, a static site needs less upkeep than a CMS with a database. Which toolchain is easier to keep current depends on whether your team already lives in Ruby or in JavaScript.
When Jekyll Is the Better Pick
- You already run a Jekyll site that works. Rebuilding it in Astro only makes sense if you need something Jekyll doesn’t do well.
- It’s a blog, documentation or project site on GitHub Pages, and the allowlisted plugins cover everything it needs.
- Your team knows Liquid and Ruby.
- The site needs posts, tags, categories and a feed, and little else.
When Astro Is the Better Pick
- Your team works in JavaScript or TypeScript, or uses React, Vue or Svelte.
- The site needs interactive components alongside mostly static content.
- Some pages or endpoints need to run on a server, such as forms, personalised pages or an API.
- You want responsive, correctly sized images by default.
- The site is likely to grow from a blog into a fuller marketing site.
If that describes your project, our Astro web development service builds sites like this, and how we work as an Astro agency shows the setup in detail. For other static generators, see Astro vs Hugo and Astro vs Eleventy.
Moving From Jekyll to Astro
Astro publishes an official guide to migrating from Jekyll. The broad picture:
- Content carries over. Markdown posts and their YAML front matter move into Astro, with fields defined in a content collection schema.
- Templates are rebuilt. Liquid layouts and includes become Astro layouts and components. Tags and category pages are rebuilt as routes.
- URLs need mapping. Astro has no
permalinksetting with placeholders, so check every existing URL against the new site and add redirects wherever one changes, so search traffic and links keep working.
The content is rarely the hard part. The templates and the URL check are where the time goes.
FAQ
Is Jekyll still maintained?
Yes. Jekyll is open source under the MIT licence, its current release is 4.4.1, and GitHub Pages still builds sites with it. It’s a mature project rather than a fast-moving one.
Does GitHub Pages support Jekyll 4?
Not in its built-in build. As of October 2026, GitHub Pages builds with Jekyll 3.10.0 and a fixed set of plugins. To use Jekyll 4 or other plugins, build the site in a GitHub Actions workflow or locally and publish the output.
Can Astro deploy to GitHub Pages?
Yes. Astro’s official withastro/action builds and deploys the site from a GitHub Actions workflow. You set the site and base values in the Astro config and choose GitHub Actions as the Pages source.
Is Astro faster than Jekyll?
For visitors, both serve static HTML, so page speed depends on how the site is built rather than which tool built it. Astro makes a light page the default by sending no JavaScript unless a component needs it. Jekyll can match that with care.
Do I need React to use Astro?
No. Astro has its own component syntax, and you can build a whole site without React. React, Vue, Svelte, Solid and Preact are optional for components that need them.
Can I move my Jekyll site to Astro?
Yes. Your Markdown content moves across, Liquid templates are rebuilt as Astro components, and URLs are mapped with redirects where they change. Astro’s documentation has a dedicated migration guide for Jekyll sites.
