Companies Using Astro

We detect Astro on 287,180 domains, including Unilever PLC, AccorHotels, Ikea Ab. A detection means the technology is present on that domain, which for large organisations is often a single storefront or subdomain rather than a company-wide deployment. Among domains we matched to a company with a resolved industry, the most common is IT Services and IT Consulting (7.86%).

We detect 287,180 domains running Astro across our monthly crawl of live business domains. Company data could be matched for 108,170 of them (37.7%), and every company-size, industry and country breakdown on this page describes that matched subset rather than the full detected base. A further 17,154 domains carried a Astro detection previously and no longer do.

Astro holds 26.13% of the Static Site Generators category, ranking #2. This is a share of the domains we detect running a platform in this category — not a share of all websites, and not a share of spending — so it is not directly comparable to figures published on other denominators.

The top alternatives to Astro include Next.js (66.6% market share), Gatsby (2.71% market share), Hugo (2.61% market share), Jekyll (0.69% market share) — measured as a share of the domains we detect running a platform in this category.

United States leads with 25,444 matched Astro domains, followed by India (6,902), United Kingdom (6,852), Brazil (6,591), Germany (6,175). These are counts within the 108,170 domains we could match to a company record, not the full detected base.

The most common company size is 1-10 employees, representing 74.43% of the Astro domains we could match to a company record and size — a subset of 108,170 matched companies, not of all 287,180 detected domains. This is followed by 11-50 employees (18.16%) and 51-200 employees (4.83%).

Among the Astro domains we could match to a company with a known founding date, the largest group was founded in the 2020s (40.79%), followed by the 2010s (38.68%). That matched subset is drawn from 108,170 companies and is not representative of all 287,180 detected domains. This suggests Astro is most popular among relatively young companies.

The ideal Astro customer is: Company Size: 1-10 employees, Location: US, India, or the UK, Industry: IT Services and IT Consulting, Founded: 2020-2026, Company Age: Under 6 years old — based on our analysis of 108,170 enriched companies at TechnologyChecker.io.

For content-heavy sites, Astro has the structural advantage. It ships zero JavaScript by default and renders pages as static HTML, while Next.js adds a React runtime to every page whether or not it is needed. Our switching data points the same way: since March 2026 we have recorded 2,128 domains dropping Next.js while running Astro, against 747 moving in the other direction. Next.js is still detected on 731,970 domains against Astro's 287,180, so this is a challenger gaining ground rather than a change of leader.

Astro works with any headless CMS, and in practice most Astro sites do not run a detectable CMS at all. In our co-occurrence data, WordPress appears on just 0.77% of Astro domains, Wix on 0.32%, Shopify on 0.20% and Webflow on 0.17%. Astro's built-in Markdown, MDX and content collections cover a large share of the content-driven sites it is used for, and headless options connect through its integration directory when a separate editing layer is needed.

Yes. Astro is a meta-framework that can use components from React, Vue, Svelte, Solid and other UI libraries on the same page. Its islands architecture renders most of the page as static HTML and only hydrates interactive components when needed. This differs from Next.js or Nuxt.js, which are tied to a single framework, React and Vue respectively.

Astro is free and open source under the MIT license. The Astro Technology Company was acquired by Cloudflare in January 2026, per Cloudflare's own acquisition announcement, and the framework remains under the MIT license with open governance and deployable anywhere. Deployment costs depend on your hosting provider; most static hosts offer a free tier for the kind of output Astro produces.

Yes. Astro supports server-side rendering and hybrid rendering modes alongside static generation, and you can mix static pages with dynamic API routes in the same project. Astro 6 introduced Live Content Collections, which update data without a full rebuild. That said, for highly interactive applications with complex client-side state, a full-stack framework such as Next.js or SvelteKit is usually the better fit, and that trade-off is the most common criticism in Astro's own review threads.

Cloudflare acquired The Astro Technology Company in January 2026, per Cloudflare's acquisition announcement. Astro team members joined Cloudflare, and the framework remains open source under the MIT license and deployable on any host. The acquisition does not tie Astro to a single platform, and our co-occurrence data reflects that: Cloudflare is the leading CDN on Astro domains at 20.99%, but roughly four in five Astro domains we profile sit somewhere else.

Very fast for content sites. Sparkbox's independent framework benchmark measured Astro at a Lighthouse performance score of 100, with Time to Interactive of 0.3s, zero Total Blocking Time and Largest Contentful Paint of 0.4s, against 180ms of Total Blocking Time and 1.7s LCP for the same component in Next.js. The reason is architectural: Astro ships no client-side JavaScript by default, so a page is static HTML and CSS until you opt a component into hydration.

Yes. Astro's islands architecture lets you use React components alongside Vue, Svelte, Solid or Preact components on the same page. React components render as static HTML by default and are only hydrated when you add a client directive such as client:load or client:visible, so you get React's component model without shipping its full runtime to every visitor.

Astro is one of the strongest options for blogs. It was built for content-driven websites and includes Markdown, MDX and content collections with schema validation out of the box, and it ships no JavaScript by default, which is where most blog performance problems come from. Our data supports the fit at scale: content-oriented sites make up the bulk of the 287,180 domains where we currently detect Astro.

In our switching data the flow runs one way. Since March 2026 we have recorded 324 domains moving from Gatsby to Astro and none moving from Astro to Gatsby. The size gap is now large as well: we detect Gatsby on 29,767 active domains against Astro's 287,180, which places Gatsby third in the static site generator category and Astro second.

We currently detect Astro on 287,180 active domains. Named examples from our crawl include Unilever (www.unilever.com), IKEA (www.ikea.com), Adobe (adobe.com), BlackRock (blackrock.com), LEGO (www.lego.com), Michelin (www.michelin.com), Ferrari (ferrari.com), Lyft (lyft.com), AMD (developer.amd.com), Kuehne + Nagel (mykn.kuehne-nagel.com), Ryanair (privatetransfers.ryanair.com), Zomato (zomato.com), ASUS (press.asus.com) and the U.S. General Services Administration (smartpay.gsa.gov). Note how many of those are subdomains: enterprise Astro usage is typically one property, a docs portal or a microsite rather than a primary corporate website. The wider base is very different, with 74.43% of the companies we can size having 10 or fewer employees.

It depends on what you are building. Astro is detected on 287,180 active domains against Hugo's 28,690, and our switching data records 138 domains moving from Hugo to Astro against 25 going back. Astro supports component-based development with React, Vue or Svelte, while Hugo uses Go templates and compiles very large sites faster. One caveat on the size comparison: these two are not detected with equal reach, so treat the ordering as more reliable than the ratio.

IT Services and IT Consulting leads at 7.86%, followed by Software Development (7.04%), Business Consulting and Services (5.22%) and Technology, Information and Internet (4.82%). Those four are all tech-adjacent and combine for 24.94% of the companies we could enrich. Astro is not confined to tech, though: Advertising Services (3.34%), Construction (2.99%), Retail (2.25%), Marketing Services (2.24%) and Financial Services (2.15%) all carry meaningful volume.

Because the chart and the headline both come from our current crawl, which measures more of the web than our earlier coverage did. We hold readings for Astro going back to its June 2021 public beta, but our coverage then and our coverage now are different enough that plotting them as one line would imply a rate of growth the data cannot support. Two things moved together over that period: the set of domains we crawl turns over every month, with dead domains dropping out and newly discovered ones coming in, and our detection signals widened. Part of the difference is Astro genuinely growing, which Astro's own year in review supports with weekly npm downloads rising from roughly 360,000 to over 900,000 during 2025. Part of it is us seeing more of the same web. They are not separable from a single number, so the chart shows three months on one consistent basis and we publish no rate across the rest.
