Deploy Astro Documentation for Free

Astro generates static output by default, which makes documentation one of the safest workloads for free hosting. Cloudflare Pages and Netlify can build from Git, publish `dist`, provide preview URLs and attach a custom domain without running a permanent server.

Keep the documentation static unless search or authentication truly needs a server runtime.

Build with `npm run build` and publish the `dist` directory.

Use Cloudflare Pages for an edge-friendly default or Netlify for its integrated site workflow.

Test base paths, redirects, sitemap and broken links in every production build.

Cloudflare Pages is the primary recommendation for this deployment path.

Deployment path

  1. 1 Set the production `site` URL in Astro configuration so canonical links and sitemap URLs are correct.
  2. 2 Run the production build locally and inspect generated routes and asset paths.
  3. 3 Import the repository into Cloudflare Pages or Netlify.
  4. 4 Set the build command to `npm run build` and output directory to `dist`.
  5. 5 Configure the custom domain, HTTPS, redirects and any environment variables.
  6. 6 Verify navigation, search index, 404 handling, canonical tags and preview deployments.

SEO checks for documentation

Give every page a unique title and description, maintain one canonical URL, expose crawlable navigation and include the sitemap in robots.txt. Redirect renamed pages rather than leaving inbound links on 404s. Static output is inexpensive, but documentation still needs deliberate information architecture.

FAQ

Can Astro documentation be hosted free?

Yes. Static Astro output is a strong fit for free Pages-style hosting and usually avoids server sleep.

Does an Astro docs site need an adapter?

Not for default static output. Install a platform adapter only when using on-demand rendering or platform-specific server features.

Which output directory should I publish?

Astro uses `dist` by default after `astro build` or `npm run build`.
