Sveltia CMS

Sveltia CMS is a leading Git-based headless CMS for Jamstack sites. It’s open source, free, and a complete modern rewrite of Netlify CMS, now known as Decap CMS, which has been incredibly neglected for years.

Designed for content editors and developers alike, Sveltia CMS delivers a great UX/DX, powerful features, and first-class internationalization (i18n) support — all in a small, maintenance-free, single-page web application served from a CDN. Its generic-purpose approach makes it suitable for a wide range of projects, from personal blogs and portfolios to marketing sites and knowledge bases.

As the successor to Netlify/Decap CMS, we continue to deal with issues reported in their repository, of which 390 have now been solved in Sveltia CMS (850 including duplicates). It incorporates numerous enhancements while maintaining high compatibility with existing installations. A growing number of projects, including U.S. government agencies, are switching from Netlify/Decap CMS to Sveltia CMS to enjoy its significantly improved performance, security, reliability, and experience.

Sveltia CMS is framework-agnostic and hosting platform-independent. It’s an excellent option for those moving away from a traditional CMS and looking for a lightweight headless CMS that works well with Astro, Eleventy, Hugo, or any other static site generator (SSG). It also works well with vanilla JavaScript and custom tooling.
