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 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 de facto successor to Netlify/Decap CMS, we continue to deal with issues reported in their repository, of which 365 have now been solved in Sveltia CMS (820 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 can also be used for vanilla JavaScript sites. It’s an excellent option for people moving away from a traditional CMS or website builder and looking for a lightweight headless CMS that works well with a static site generator (SSG) like Astro, Eleventy, or Hugo.
