Sveltia CMS

Sveltia CMS is a modern, free, Git-based headless CMS built as a complete rewrite of Decap CMS. It is lightweight — under 500 KB — and designed to be significantly faster than its predecessor .

Sveltia has resolved over 345 issues inherited from the Decap/Netlify CMS codebase, offering a cleaner, more reliable editing experience. It is actively maintained and includes built-in internationalization support and better mobile compatibility.


Like Decap, Sveltia CMS is Git-based. It commits content directly to your repository, and Astro builds the final site from those files. The admin interface is served from your deployed site and communicates with your Git provider for authentication and content operations.

Sveltia is designed to be highly compatible with existing Decap CMS configurations. If you have a Decap setup, Sveltia can often work with the same content structure without major changes .

Key characteristics:

  • Git-based — content lives in your repository
  • Static admin UI — no backend server required
  • Compatible with Decap-style content organization
  • Fast — optimized for performance and mobile
  • Open source — free to use

CompatibilityWorks with Decap configsBaseline

For teams still using Decap but frustrated by its performance or maintenance pace, Sveltia is the natural upgrade path.


Sveltia CMS is a good fit if you:

  • Want a Git-based CMS without a separate database
  • Need a fast, modern editing interface
  • Prefer an actively maintained open-source option
  • Have mobile editors on your team
  • Want compatibility with existing Decap workflows

It may not be ideal if you:

  • Need visual editing with live previews (consider Tina Cloud)
  • Require enterprise support with SLAs
  • Are locked into a proprietary CMS ecosystem

Sveltia CMS integration is a service, not a built-in feature of Astro Docus. The template ships with the content structure ready for CMS integration, but the setup requires configuration specific to your repository, hosting, and authentication method.

If you need help setting up Sveltia CMS for your Astro Docus site — including authentication, content configuration, and migration from Decap — professional setup services are available.
