The best CMS for Astro in 2026
Astro sites are fast to build and, by default, edited in code. If someone else needs to change the content, these are the ten options worth knowing, with what each needs from you and what it costs.
Siteshare
An editor at the site's own address, /edit. Clients chat, select or draw on the real site; every publish is build-checked and lands as one commit on main.
- Best for
- Sites you build and hand over to a client who changes things now and then.
- Price
- Free for 1 site; then $9 a site a month, down to $4 as you grow (5 sites $36, 20 sites $126); clients and builders unlimited. VAT is added where it applies.
- Keep in mind
- Sites on GitHub only. No structured content API for other channels.
Keystatic
An open-source editor for Markdown, JSON and YAML in your repository, with forms at /keystatic.
- Best for
- Developers who want a free, Git-based editor without a database.
- Price
- Free (MIT). Keystatic Cloud free up to 3 users; Pro from $10 a month per team.
- Keep in mind
- Needs a keystatic.config.ts with collections; Astro needs a server adapter to run it.

- Best for
- Typed, structured content in Git, with visual editing for editors.
- Price
- Free (2 users); Team $24, Team Plus $41, Business $249 a month per project.

Decap CMS
An open-source form editor (formerly Netlify CMS) that commits through your Git host's API.
- Best for
- Well-defined entries like posts and events, on a zero budget.
- Price
- Free (MIT). Hosted Decap Turbo: free, or Pro €19 a month.

- Best for
- Small static sites where non-technical people fill in content.

- Price
- Standard $55 a month ($49 yearly, 3 users); Team $350 ($300 yearly, 15 users). No free plan.

A hosted headless CMS with a visual editor that shows your site beside the fields.
- Best for
- Block-based pages edited visually by marketing teams.
- Price
- Starter free (1 seat); Growth €99, Growth Plus €349 a month per space.

- Best for
- Teams that want one content API for a site and apps.
- Price
- Self-hosted free; Growth $45 a month; Cloud from $35 a month per project.
- Keep in mind

How to choose
Start with one question: who edits, and how often?
- A client who changes something a few times a month needs as little to learn as possible. Siteshare, or a Git-based editor with a small config, keeps the site as it is.
- An editor who publishes posts every week is well served by forms on a clear content model: Keystatic, TinaCMS, Decap or Pages CMS.
- A team that reuses content across a site and apps benefits from a headless platform: Storyblok, Sanity, Contentful or Strapi. Expect to wire the site to its API.
Where the content lives
Git-based tools (Siteshare, Keystatic, TinaCMS, Decap, Pages CMS, CloudCannon) keep content in your repository, so your Astro build stays simple and your history in one place. Headless platforms keep it in their own store and serve it through an API, which pays off when many channels use the same content.
Questions
What is the best free CMS for Astro?
For content in Git: Keystatic, Decap CMS and Pages CMS are free and open source. Siteshare is free for one site and needs no configuration. Storyblok, Sanity and Contentful have free tiers with limits.
Do I need a headless CMS for an Astro site?
Only if your content is reused across several channels or edited daily by a team. For a site a client changes now and then, a Git-based editor or Siteshare keeps everything in your repository.
Which CMS lets a client edit text inside Astro components?
Git-based CMSs reach the collections and files you configure. Siteshare edits the components themselves, because the assistant reads and changes the code where the text lives.
