What Sveltia CMS is
Sveltia CMS is a free, open-source, Git-based headless content management system for Jamstack development. It runs in a browser as a JavaScript application served through a CDN, without a database, server, or build tool. Content can be stored and versioned with GitHub, GitLab, Gitea, or Forgejo, and edited in Markdown, YAML, JSON, or TOML. A JavaScript API lets developers add custom fields, previews, and editor components. The interface offers dark mode, keyboard shortcuts, drag-and-drop uploads, full-text search, accessibility features, and mobile and tablet support. For media, it includes an asset library and supports external storage, stock-photo services, and image optimization such as WebP conversion. It also supports multilingual content and one-click AI translation through services including Google Cloud Translation, Anthropic, and OpenAI. Sveltia CMS is free for personal and commercial use; no account or subscription is required. The maker positions it mainly for experienced web developers and small to medium-sized projects. It is in beta, and breaking changes may occur before stable 1.0.
