Companies Using Astro

With 10+ years in web crawling and technographic data analysis, I've examined Astro's trajectory using our enriched dataset of 22,133 companies matched from 49,623 active domains (a 44.6% match rate). The analysis combines our April 2026 crawl data with vendor-published case studies from Cloudflare and Astro's own documentation. Here's what the numbers reveal about Astro's rise and what it means for sales teams targeting this ecosystem.

Growth trajectory

Astro's adoption curve is one of the steepest we've tracked. From 29 active domains in July 2021 (when the framework launched) to 38,861 at peak in April 2025, that's a 1,340x increase in under four years. The real inflection point came in mid-2023: Astro went from 151 domains in May to 786 in July, then hit 5,237 by December. The Astro 3.0 release and growing discontent with Next.js complexity both contributed to this surge.

Community metrics reinforce the trajectory. npm downloads grew from approximately 360,000 to over 900,000 weekly downloads during 2025, a 2.5x increase, per Astro's year-in-review. GitHub stars hit 55,200 (up 7,000 in 2025 alone). The 2025 Stack Overflow Developer Survey ranked Astro the 4th most admired web framework at 62.2%, and GitHub's Octoverse 2025 report named it one of the fastest-growing languages on the platform. The slight pullback from 38,861 (April 2025) to 35,912 (July 2025) in our crawl data is worth watching but isn't alarming given these broader signals.

"Astro's growth rate is unlike anything I've seen in the SSG space. It went from barely registering in our crawl data to becoming the #1 pure static site generator in less than three years. The Cloudflare acquisition in January 2026 could accelerate this further." - Mehmet Suleyman, CEO at TechnologyChecker.io

Sales Signal: The framework is in a rapid expansion phase. Companies adopting Astro right now need migration support, developer training, and tooling integrations. Target agencies and dev shops that build client sites; they're the multiplier effect behind Astro's growth.

Customer profile

Astro's user base is overwhelmingly small and young: 85.1% have 1-10 employees and 52.3% were founded in the 2020s. Combined, 84.3% of Astro companies were founded after 2010. This is a digital-native framework for digital-native companies.

But the enterprise tail is more interesting than it looks. Our detection data shows 147 companies with 10,001+ employees using Astro, including Deloitte, Wells Fargo, AT&T, IKEA, Visa, and Bloomberg. Cloudflare's acquisition announcement specifically named Porsche, IKEA, and OpenAI as Astro users. Microsoft built its Fluent 2 design system site with Astro, per Astro's published case studies. WP Engine reported lowering development costs by over 50% using Astro's Starlight, and Firebase cut blog publishing time from hours to minutes after switching. Beyond direct adoption, Astro has become the default framework for several platforms: Webflow Cloud and Wix Vibe both use Astro for customer-built sites deployed on Cloudflare's network, and Stainless generates Astro-powered developer documentation sites, per Cloudflare's acquisition blog post. CodeTV, a subscription video streaming platform built by Jason Lengstorf, shows Astro working beyond static content with Mux, Clerk, Stripe, and Sanity integrations. These enterprise deployments are typically on subdomains (design.visa.com, maxjapan.adobe.com, genome.genpact.com) rather than primary corporate sites, suggesting Astro fills a specific niche: fast, content properties within larger tech stacks.

Sales Signal: Two distinct buyer profiles exist. The primary market is small teams (1-10 people) building their first or second website. The secondary market is enterprise dev teams choosing Astro for specific properties. Sales motions differ: self-serve and community-driven for the first, procurement-driven with security questionnaires for the second.

Industry and geographic concentration

The top four industries are all tech-related: IT Services (7.06%), Software Development (6.94%), Business Consulting (5.88%), and Technology/Internet (4.82%). Together they account for 24.7% of the user base. This isn't surprising for a developer framework, but the long tail is notable: Construction (2.41%), Retail (2.31%), and Financial Services (2.18%) all have meaningful presence.

Geographically, the US leads at 18.9% but it's not dominant the way it is for most frameworks. Brazil (2,240 companies) and India (1,713) are #2 and #3. Latin America collectively accounts for 13.9% of users, which reflects Astro's strong community engagement in Portuguese and Spanish-speaking markets. English-speaking countries (US, UK, Canada, Australia) combine for about 28.5% of the total, far below the 50%+ we see for most enterprise tools.

Sales Signal: The LatAm footprint represents an underserved market. Brazilian and Indian companies adopting Astro likely need localized hosting, payment, and analytics solutions. Selling into the US enterprise tier is more competitive but higher-value per deal.

Migration patterns

Astro has net positive migration from every major competitor. The biggest corridor: 1,014 companies came from Next.js while only 558 went the other direction, a 1.8:1 gain ratio. The Gatsby numbers are striking: 368 companies migrated to Astro while just 30 moved to Gatsby, a 12.3:1 ratio that reflects Gatsby's accelerating decline after its parent company Netlify shifted focus.

Nuxt.js shows a 3:1 ratio in Astro's favor (386 gained vs. 130 lost). Hugo, the Go-based SSG, shows a 5.3:1 ratio (137 gained vs. 26 lost). Across all tracked competitors, Astro gained 1,905 companies and lost 744, for a net gain of 1,161 companies.

"The Gatsby-to-Astro migration corridor at 12:1 is the most lopsided ratio we've measured in the SSG category. Gatsby users aren't just leaving; they're overwhelmingly choosing Astro as their destination." - Mehmet Suleyman, CEO at TechnologyChecker.io

Sales Signal: Companies migrating from Gatsby and Next.js need two things: migration tooling and content about why Astro is better for their use case. Astro's own docs include migration guides from Next.js, Gatsby, and Hugo. Build on those with data-backed case studies showing performance improvements post-migration.

Technology ecosystem

Astro users lean heavily into the Cloudflare ecosystem: Cloudflare Radar (6.26%) and Cloudflare Web Analytics (4.92%) are the most common co-occurring technologies. This isn't just a post-acquisition signal; Cloudflare Pages was already the most popular deployment target for Astro before January 2026. Per Cloudflare's own blog, they run their developer docs (developers.cloudflare.com), main website (workers.cloudflare.com), landing pages (sandbox.cloudflare.com), and blog (blog.cloudflare.com) on Astro.

For user behavior analytics, Microsoft Clarity (3.59%) edges out Hotjar (3.38%). In the JavaScript framework layer, AngularJS (2.18%) and Svelte (1.27%) appear often. The Svelte overlap is interesting because Astro's island architecture supports Svelte components natively, so these aren't competing frameworks on the same site; they're working together.

Sales Signal: The Cloudflare analytics dominance leaves room for competitors. Only 3.59% use Microsoft Clarity and 3.38% use Hotjar, meaning most Astro sites have no user behavior analytics at all. That's a gap for analytics vendors targeting developer-built sites.

Performance and developer sentiment

Third-party benchmarks validate what the adoption numbers suggest. Sparkbox's independent framework comparison measured Astro at a Lighthouse performance score of 100, with Time to Interactive of 0.3s, zero Total Blocking Time, and LCP of 0.4s. By comparison, the same test component in Next.js produced 180ms TBT and 1.7s LCP.

Developer surveys tell a similar story. The State of JS 2025 placed Astro #1 in meta-framework satisfaction with a 39 percentage point lead over Next.js. The 2025 Stack Overflow Developer Survey ranked it the 4th most admired web framework at 62.2% of 23,678 respondents. GitHub's Octoverse 2025 report named Astro one of the fastest-growing languages on the platform.

Sales Signal: Performance data makes a concrete sales pitch. "Astro sites score 100 on Lighthouse with 0.3s TTI" is a measurable claim that resonates with marketing teams focused on Core Web Vitals. Pair this with WP Engine's published 50%+ cost reduction to build ROI-focused outreach.

Key takeaways

1. Astro grew 1,340x in four years and is the #1 pure static site generator by active domains.

2. The user base is 85% micro-businesses and 52% companies founded in the 2020s, making it the youngest-skewing framework we track.

3. Enterprise adoption exists (147 companies with 10,001+ employees) but is niche: design systems, dev docs, and microsites, not primary corporate infrastructure.

4. Astro gains from every competitor, with the Gatsby corridor showing a 12:1 ratio. Next.js migration is the highest volume at 1,014 companies.

5. Latin America (Brazil, Mexico, Colombia, Argentina) accounts for 13.9% of users, a distinctly international profile compared to peer frameworks.

6. Webflow Cloud and Wix Vibe chose Astro as their default framework for customer sites, signaling platform-level confidence in the framework.

7. The Cloudflare acquisition in January 2026 could accelerate both adoption and enterprise credibility.
