Best CMS for Astro: 5 Options for Beginners Compared
The best content management systems for Astro, from EmDash to Keystatic and Sanity, and how to pick one without overthinking it.
In this guide
A CMS gives you a dashboard for writing, so you don’t have to edit files. Astro works with dozens of them. The official docs list more than forty.
Here are five we’d consider first, and a simple way to choose. We checked each project’s official site on November 6, 2026. We’ve installed EmDash and used Astro’s own content system; the others are described from their documentation.
The short answer
- Want a full dashboard, built for Astro: EmDash
- Want to keep content in your project as files: Keystatic
- Want a free, simple editor for a static site: Decap CMS
- Want a hosted service with a polished editor: Sanity
- Already have WordPress: keep it as a headless CMS
1. EmDash
EmDash is Cloudflare’s open-source CMS, and it’s built on Astro itself. You get a full dashboard, user roles, a media library and a WordPress importer. It runs on Cloudflare or on a Node.js server.
It’s the most “WordPress-like” option on this list, and the newest. Read what is EmDash and how to install it.
Choose it if: you want a dashboard and you’re staying in the Astro world.
2. Keystatic
Keystatic is a free, open-source CMS that stores your content as files in your project, in Markdown, YAML or JSON. You edit through a local admin screen, or through GitHub so your team can edit online.
Because the content stays in your repository, your site can still be fully static and hosted anywhere.
Choose it if: you like the idea of content as files, but want an editor on top.
3. Decap CMS
Decap CMS, formerly Netlify CMS, is a free, open-source editor that lives at /admin on your site. It saves edits straight to your Git repository, and it’s configured with a single file.
It’s been around for years, and it’s a common first CMS for static sites.
Choose it if: you want a simple, free editor for a static site and don’t mind a bit of setup.
4. Sanity
Sanity is a hosted, API-based CMS with a customizable editor. Your content lives on Sanity’s servers, and your Astro site fetches it. It has an official Astro integration and a free plan with limits.
Choose it if: you want a polished editing experience and don’t mind depending on a service.
5. WordPress as a headless CMS
If you already run WordPress, you can keep its dashboard and let Astro display the content through the WordPress REST API. Your editors change nothing, and your visitors get a faster site.
Choose it if: your team lives in WordPress and you want a gradual move. See how to move from WordPress to Astro.
How to choose
Ask three questions:
- Who edits? Just you: skip the CMS and use Markdown, or use Keystatic. Other people: EmDash, Decap or Sanity.
- Where should content live? In your project: Keystatic or Decap. In a database or service: EmDash or Sanity.
- Does the site need to stay static? Yes: Keystatic or Decap. No: any of them.
Still unsure? Start without a CMS. Astro’s built-in content collections handle a blog well, and you can add a CMS later when editing files gets in the way.
Frequently asked questions
Do I need a CMS for my Astro site?
Not if you're the only editor and you're happy writing Markdown files. A CMS is for sites where other people need to publish, or where you want a dashboard.
What is a headless CMS?
A CMS that stores and edits your content but doesn't display it. Your Astro site fetches the content and shows it. Most CMS options for Astro work this way.
Which CMS is free?
EmDash, Keystatic, Decap CMS and WordPress are free software. Hosted services like Sanity have free plans with limits, so check their pricing pages.
