Astro is a modern framework for building fast websites — above all the kind where content, loading speed and technical tidiness matter. Business websites, blogs, documentation, media sites, landing pages, light shops. That’s where Astro gives you the most.
Unlike traditional CMSs such as WordPress, Astro doesn’t try to handle every scenario and every kind of site. It focuses on making the finished site light, fast and simple to maintain. It isn’t another page builder or admin panel. It’s a tool for people who prefer to have control over the structure of their site and don’t want scripts, themes and plugins that nobody uses loading underneath.
How does Astro work?
The core idea of Astro is rendering static HTML at build time. Instead of generating pages on every visit (as WordPress and other traditional CMSs do), Astro builds the finished HTML files ahead of time — when the project is compiled. The browser immediately receives light, ready-to-display code, and the server doesn’t have to generate anything again.
The second thing that sets Astro apart is the approach known as Islands Architecture. An Astro page is static by default — with no client-side JavaScript at all. Interactive elements (a mobile menu, a form, a slider) work as separate “islands” and only load the code that’s actually needed in that particular place. It sounds technical, but the practical effect is simple: sites built on Astro carry a minimal amount of JavaScript, load quickly and don’t drain your phone’s battery.
The third element is flexibility over components. With Astro you can use React, Vue, Svelte or Solid, or stick with the native .astro component — you decide what makes sense for a given project. Most simple business websites don’t need any of those libraries, and Astro is a perfect fit for that.
Who builds sites on Astro?
Astro isn’t a niche technology. It’s used by large, recognisable brands — mostly where speed and content quality matter.
Logos are trademarks of their respective owners. The full list of companies is at astro.build/showcase.
The Guardian — one of the largest English-language newspapers — moved to Astro in 2024 so its authoring system could publish content faster and with better Core Web Vitals. Netlify, one of the biggest hosts for modern websites, uses Astro on its own sites. Trivago built its trv.land magazine in Astro. Firebase (Google) uses Astro for its documentation. IKEA uses Astro on selected pages of its national sites. NordVPN built a help centre on Astro.
The list of companies using Astro is growing fast. That’s a good sign the tool isn’t an experiment or hype — it holds up in environments where site performance translates into real money.
What kind of sites does Astro make sense for?
Astro isn’t a tool for everything. Where you need an admin panel for several editors, complex logged-in user logic or a dynamic app with hundreds of interactions, other solutions are better.
But for typical web projects, Astro is a near-perfect fit:
- Business and service websites — a few pages, your services, a contact form, a blog. All static, fast and easy to maintain.
- Campaign landing pages — one goal, minimal code, near-instant loading even on a weak connection.
- Blogs and content sites — Markdown as the content source, ready-made templates, SEO out of the box.
- Technical documentation — this is exactly what the Astro community is known for (Starlight, the official docs of many tools).
- Light shops — when you don’t need full-blown e-commerce, you can build a fast Astro front end and base the selling on proven payment gateways or an external API.
If your site is mostly there to inform, present your offer and encourage people to get in touch, Astro will almost always be a lighter, faster and simpler choice than a traditional CMS.
Astro vs WordPress — how do the approaches differ?
WordPress was designed two decades ago, when managing a site meant logging into a panel and clicking. It worked brilliantly for bloggers, editorial teams and small businesses that needed to edit content themselves. Over time it grew into a “do-everything” machine.
Astro flips that logic. Instead of one powerful system that has to handle every case, you get a light tool that creates exactly what’s needed — and nothing more. The content can live in Markdown files, a database, an external headless CMS or a spreadsheet. The site always reaches the visitor as finished, fast HTML.
In short: WordPress loads everything every time. Astro builds once and sends the finished result. For most business websites, the second strategy makes more sense.
We’ve covered this comparison in detail (when each strategy makes sense and when it doesn’t) in a separate article: Why Astro instead of WordPress?
When is Astro NOT the best choice?
To be honest: there are projects where Astro would only get in the way. It’s worth knowing that up front.
- Complex web apps with dozens of real-time interactions (a SaaS dashboard, an online editor) — frameworks like Next.js, Remix or SvelteKit are a better fit there.
- Large e-commerce with hundreds of products, variants, stock and ERP integration. Here traditional solutions such as Shopify, WooCommerce or a dedicated back end still make sense.
- Sites the client edits every day without a developer. Astro can be paired with a headless CMS (Sanity, Storyblok, Contentful, Decap), but that takes extra setup and won’t replace a full WordPress panel for a non-technical user.
- Projects based mainly on user-generated content — forums, social networks, comments, content loaded live.
For everything else — a typical business website, a landing page, a blog, a presentation of your offer — Astro is a very good choice.
What does Astro look like in practice at Astrofy?
At Astrofy we build sites with Astro and Tailwind. No heavy page builders, no excess plugins, no code “just in case”. We start every project by asking what the site actually needs to achieve, and only then choose the solution.
The outcome is consistent: light sites, good PageSpeed scores, readable code and a simple process for rolling out changes. Whether you need a business website, a landing page or a light online shop, Astro is a great base for a modern, fast site. The framework keeps evolving — on the blog we cover what’s new in Astro 6.3.
