Sveltia CMS
Sveltia CMS is a free, open-source, Git-based headless content management system for Jamstack sites. It’s a complete rewrite of Netlify CMS, now known as Decap CMS.
Designed for content editors and developers alike, Sveltia CMS delivers a modern 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 CMS, Sveltia CMS addresses 300+ issues and introduces numerous enhancements while maintaining high compatibility with existing installations. It far surpasses the neglected official successor, Decap CMS. More and more projects, including a U.S. government website, 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 a great choice for people leaving a traditional CMS or website builder and looking for a lightweight headless CMS that seamlessly integrates with a static site generator (SSG), such as Astro, Eleventy, and Hugo.
