Best CMS for Astro: 5 Options for Beginners Compared

A CMS gives you a dashboard for writing. So you don’t have to edit files. CMS stands for content management system. Astro works with dozens of them. The official docs list more than forty.

Here are five we would look at first. And a simple way to choose. We checked each project’s official site on November 6, 2026. We have installed EmDash. We have used Astro’s own content system. The others are described from their docs.

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. It is built on Astro itself. Open source means the code is free for anyone to use. 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 is the most “WordPress-like” option on this list. It is also the newest. Read what is EmDash and how to install it.

Choose it if: you want a dashboard and you are staying in the Astro world.

2. Keystatic

Keystatic is a free, open-source CMS. It stores your content as files in your project. The files are Markdown, YAML or JSON. You edit through a local admin screen. Or you edit through GitHub, so your team can edit online.

The content stays in your repository. A repository is the saved history of your project’s files. So your site can still be fully static and hosted anywhere. A static site is made of finished pages that do not change.

Choose it if: you like content as files, but want an editor on top.

3. Decap CMS

Decap CMS used to be called Netlify CMS. It is a free, open-source editor that lives at /admin on your site. It saves edits straight to your Git repository. Git is the tool that tracks changes to your files. You set it up with a single file.

It has been around for years. It is 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 CMS. Your content lives on Sanity’s servers. Your Astro site fetches it through an API. An API is a way for two programs to talk. You can customize the editor. 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

Already run WordPress? You can keep its dashboard. Astro then shows the content through the WordPress REST API. Headless means the CMS stores the words, and Astro displays them. Your editors change nothing. Your visitors get a faster site.

Choose it if: your team lives in WordPress and you want a slow, steady move. See how to move from WordPress to Astro.

How to choose

Ask three questions:

1. Who edits? Just you: skip the CMS and use Markdown, or use Keystatic. Other people: EmDash, Decap or Sanity.
2. Where should content live? In your project: Keystatic or Decap. In a database or service: EmDash or Sanity.
3. 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. 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 are the only editor and you are 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 does not 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.
