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, outstanding DX, powerful features, and first-class internationalization (i18n) support — all in a small, maintenance-free, single-page web application served from a CDN. Its framework-agnostic, generic-purpose design makes it suitable for a wide range of projects, from personal blogs and marketing sites to product catalogs and knowledge bases.

As the de facto successor to Netlify CMS, Sveltia CMS addresses hundreds of longstanding issues while maintaining high compatibility with the existing configuration format and API. It far surpasses the official successor, Decap CMS, which has been neglected for years. An increasing number of projects, including a U.S. government site, are switching from Netlify/Decap CMS to Sveltia CMS to take advantage of its significantly improved experience, performance, security, and reliability.

Sveltia CMS is also an excellent option for individuals or organizations migrating from a traditional CMS like WordPress to a static site generator like Astro and looking for a lightweight CMS solution to manage their content.
