Astro Anleitung Best Headless CMS for Astro (2026)
Compare the best headless CMS options for Astro. We review Sanity, Contentful, Storyblok, and more with content collections integration and static site generation.
Astro's content-first architecture makes it perfect for CMS-driven sites. Content Collections give you type-safe local content, but a headless CMS enables non-developers to manage content. The best CMS for Astro integrates with your build process and optionally supports on-demand rendering.
Warum es wichtig ist
Astro excels at content sites—blogs, documentation, marketing pages. A CMS lets marketing teams update content without developer involvement. The right CMS choice affects whether you can use static generation (fastest) or need server rendering (more dynamic).
Wichtige Überlegungen
Build-time vs Runtime
Static sites fetch CMS data at build time. For preview and frequent updates, you may want Astro's SSR mode with on-demand CMS fetching. Some CMSs support both patterns well.
Preview Mode
Content editors need to preview changes before publishing. Astro supports preview/draft mode, but CMS integration complexity varies.
Visual Editing
Storyblok and Sanity offer visual editing where editors click on the page to edit. This is transformative for non-technical teams.
Content Collections Sync
Astro's Content Collections are local files. Some tools (Keystatic) bridge CMS and local content. Others are purely API-based.
Build Performance
Large sites with thousands of pages need efficient CMS fetching. Incremental builds and smart caching reduce build times.
