How many websites use Astro?

1,504,509 live websites use Astro in BuiltWith’s report retrieved on 6 October 2026. Wappalyzer separately reports 360,000 live websites on the same retrieval date.

Both services detect Astro on public websites, but their coverage and detection systems differ. Their public reports do not reconcile the gap. Neither count is a census of every Astro project, and adding them would count some sites twice.

BuiltWith lists redirects and past detections separately. Its live-site figure excludes those categories. A locally developed project or a private application may never appear in a public-web detection report.

What percentage of websites use Astro?

W3Techs reports Astro on 0.2% of all websites in its survey and 0.3% of websites with a known content management system, retrieved on 6 October 2026. W3Techs places Astro in its content management category.

The first percentage includes sites without an identified CMS. The second uses only sites where W3Techs identifies one. Neither is Astro’s share of JavaScript developers or static site generators.

W3Techs surveys websites with meaningful content or functionality, excludes redirects and treats subdomains as part of the same website. Those rules help explain why its percentages cannot be applied to BuiltWith’s count to calculate the size of the web.

How many times is Astro downloaded?

The astro package recorded 6,711,433 npm downloads from 29 September to 5 October 2026. For the last complete calendar month, it recorded 23,953,380 downloads from 1 to 30 September 2026. Both API responses were retrieved on 6 October 2026.

These are package downloads. Repeat installations, automated builds and updates can generate downloads without adding a new developer or website. The weekly and monthly windows overlap, so they should not be added together.

How large is Astro’s GitHub project?

The withastro/astro repository had 63,075 stars when checked on 6 October 2026. The contributors API returned 1,244 contributor records with anonymous contributors included. That count can include automated accounts and separate commit identities; it does not establish a total of individual people.

The latest non-prerelease entry for the core astro package in the retrieved release list was astro@7.3.6, published on 6 October 2026. The repository also publishes releases for adapters and other packages, so its full release history is broader than the core framework.

What do developer surveys say about Astro?

State of JavaScript’s 2025 results report Astro at 27% usage, 84% awareness and a 94% satisfaction ratio. These are the survey’s published, rounded ratios, retrieved on 6 October 2026. Usage describes respondents who have used Astro; awareness describes respondents who know of it. Satisfaction is a separate sentiment measure among users.

The Stack Overflow figures describe extensive development work over the past year, from its web frameworks and technologies question. Its all-respondent result covers people who answered that question. State of JavaScript attracts a more specialised JavaScript audience, and the surveys ask different questions. Their usage percentages should not be treated as competing measurements of the same population.

These are findings from the 2025 surveys, available to readers in 2026. State of JavaScript describes its audience as a self-selected subset of developers.

Where can you find Astro integrations and themes?

Astro maintains directories of integrations and free and paid themes. The integrations directory includes support for React, Vue and Svelte, along with tools for sitemaps, content and deployment. Directory listings describe available tools and designs; they do not measure how many sites use them.

Which organisations use Astro?

Cloudflare says it uses Astro for its developer documentation, website, landing pages and blog. Its announcement also identifies Porsche, IKEA, Opencode and OpenAI as adopters, and Webflow Cloud and Wix Vibe as platforms using Astro for customer websites. These examples establish particular uses of Astro without implying that every site or application belonging to each organisation runs on it.

How these numbers are measured

• Website detections: observations within each provider’s coverage. Different crawls, technology signatures and rules for grouping sites can produce different results.
• Market share: percentages within W3Techs’ defined website sample and technology category.
• Downloads and GitHub activity: package distribution and repository participation, each with its own unit of measurement.
• Surveys: reported experience and opinions from participating developers. The survey year is separate from the date these results were retrieved.

No worldwide website total or growth rate has been extrapolated from these datasets.
