What it is

Sveltia CMS is a free, open-source, Git-based headless content management system for Jamstack web development. It runs in a browser as a CDN-served JavaScript application, so it needs no database, server, or build tool. Content and version history can be stored through GitHub, GitLab, Gitea, or Forgejo. The editor handles Markdown, YAML, JSON, and TOML, with a JavaScript API for custom fields, previews, and editor components. It includes visual editing, live preview, approval workflow, dark mode, keyboard shortcuts, drag-and-drop uploads, search, accessibility features, and mobile and tablet support. Multilingual content and one-click AI translation are supported through Google Cloud Translation, Anthropic, and OpenAI. Media tools include an asset library, external storage, stock-photo services, and WebP conversion. Sveltia is self-hosted, free for personal and commercial use, and in beta; breaking changes may occur before version 1.0.
