Introduction
Static site generators (SSGs) have revolutionized how developers build websites by combining the flexibility of modern development workflows with the speed and security of static HTML. The choice of SSG affects your development experience, build times, hosting options, and long-term maintainability. This guide compares three of the most popular SSGs — Hugo, Eleventy, and Astro — to help you choose the right tool for your is-pro.dev subdomain project.
Prerequisites
- Basic familiarity with the command line and Git
- A code editor (VS Code, Sublime Text, or similar)
- An is-pro.dev subdomain to deploy your site
- Understanding of HTML, CSS, and basic templating concepts
Hugo: Speed Above All
Hugo is the fastest static site generator, capable of building thousands of pages in seconds. Written in Go, it has no runtime dependencies — you download a single binary and start building. Hugo's template system uses Go templates, which have a learning curve but offer powerful features like shortcodes, content adapters, and menu management. Hugo excels at content-heavy sites: documentation projects, blogs with hundreds of posts, and large corporate sites. Its built-in asset pipeline handles SCSS/SASS compilation, image processing, JavaScript bundling, and fingerprinting without third-party tools. The theme ecosystem is mature, with hundreds of free and premium themes. Hugo's content organization is file-based using front matter in Markdown, with taxonomies for categorizing content. The main downside is that Go templates can be verbose, and Hugo's configuration is YAML-based with less community support for non-standard setups.
Eleventy: Simplicity and Flexibility
Eleventy (11ty) prides itself on being a simpler alternative to more complex SSGs. It does not impose a specific template language — you can use Nunjucks, Liquid, Handlebars, EJS, Pug, or plain HTML, even mixing them within the same project. This flexibility makes Eleventy an excellent choice for developers transitioning from different frameworks. Eleventy outputs zero client-side JavaScript by default, keeping your sites lean and fast. Its configuration is JavaScript-based (an .eleventy.js file), giving you full programmatic control over collections, filters, and build processes. Eleventy's ecosystem supports plugins for RSS feeds, sitemaps, image optimization, and syntax highlighting. It handles small to medium-sized sites well, but build times can become noticeable beyond a few thousand pages. Eleventy is ideal for portfolios, simple blogs, and marketing sites where simplicity and output quality matter more than build speed.
Astro: Component-Based Architecture
Astro represents the next generation of static site generators, combining a component-based architecture with zero-JS output by default. You build pages using Astro components (which support JSX-like syntax), and Astro renders them to static HTML at build time. What sets Astro apart is its ability to use components from React, Vue, Svelte, or Solid.js within the same project — you can import a React component alongside a Svelte component, and Astro handles the rendering. This makes Astro perfect for teams migrating from a specific framework or projects that need to reuse existing components. Astro's islands architecture lets you selectively hydrate interactive components on the client while keeping the rest of the page static. It supports Markdown and MDX for content, has built-in image optimization, and provides RSS, sitemap, and SEO integrations. The main trade-off is that Astro is newer, so its plugin ecosystem is smaller than Hugo's or Eleventy's.
Comparison by Use Case
For a documentation-heavy project or blog with hundreds of posts, Hugo's build speed and mature feature set make it the clear winner. For a developer portfolio or simple marketing site where simplicity and output quality are priorities, Eleventy provides the most straightforward path from project start to deployment. For a site that needs interactive components from multiple frameworks (React + Vue together), or a team that already knows a component framework and wants to adopt a static site, Astro offers unique advantages. All three generators produce static HTML that can be hosted on any free platform — GitHub Pages, Vercel, Netlify, or Cloudflare Pages — paired with your is-pro.dev subdomain.
Deployment Considerations
All three SSGs deploy the same way: you build the site locally (or via CI), generating an output folder (public for Hugo, _site for Eleventy, dist for Astro), and deploy that folder to your hosting platform. GitHub Actions, Vercel, Netlify, and Cloudflare Pages all support automatic builds triggered by Git pushes. Hugo builds complete in seconds even for large sites, reducing CI wait times. Eleventy and Astro take longer for larger sites but still build in under a minute for most projects. Configure your hosting platform's build command and output directory, connect your is-pro.dev subdomain via a CNAME record, and your site is live with automatic SSL.
Best Practices
- Choose the SSG that matches your content structure and team skills rather than chasing the newest tool
- Use Git-based content management — all three SSGs work well with headless CMS options like Forestry or Decap CMS
- Optimize images at build time using each SSG's built-in image pipeline for faster page loads
- Configure incremental builds for large sites to reduce build times during development
Conclusion
Hugo, Eleventy, and Astro each excel in different scenarios. Hugo offers unmatched speed for content-heavy sites, Eleventy provides simplicity and template flexibility, and Astro delivers a modern component architecture with multi-framework support. All three pair perfectly with an is-pro.dev subdomain and free hosting platforms, giving you a professional web presence without infrastructure costs.
FAQ
Can I switch between SSGs after my site is already built?
Yes, since all three output static HTML, you can migrate content and rebuild with a different SSG. The effort depends on how your content is structured — Markdown front matter is broadly compatible.
Which SSG has the best image optimization?
Astro and Hugo both have excellent built-in image processing. Eleventy requires a plugin (eleventy-img) for image optimization, which is well-maintained and powerful.
Do I need to know JavaScript to use these SSGs?
Hugo does not require JavaScript — everything is configured with YAML/TOML and Go templates. Eleventy and Astro use JavaScript for configuration but the templates can be HTML-only or use template languages that do not require JS knowledge.
FAQ
Is Tools setup free on is-pro.dev?
Yes, all subdomains on is-pro.dev include free DNS management and SSL certificates.
How long does DNS take to propagate?
Cloudflare typically propagates DNS changes within seconds to a few minutes globally.
Can I use this for commercial projects?
Yes, is-pro.dev subdomains can be used for personal and commercial projects within our fair use policy.
