Sveltia CMS
What Sveltia CMS is
Sveltia CMS is a free, open-source, Git-based headless CMS for Jamstack web development. It runs in a browser as a CDN-served JavaScript application and requires no database, server, or build tool. Content is stored and versioned through GitHub, GitLab, Gitea, or Forgejo, and editors can work with Markdown, YAML, JSON, or TOML. A JavaScript API supports custom fields, previews, and editor components. The interface includes a visual editor, live preview, approval workflow, dark mode, keyboard shortcuts, drag-and-drop uploads, full-text search, and mobile and tablet support. It also supports multilingual content and one-click AI translation through Google Cloud Translation, Anthropic, and OpenAI. Media tools include an asset library, external storage, stock-photo services, and image optimization such as WebP conversion. The maker says the CMS collects no user data or analytics and sends no data to maker-operated servers. It is in beta, and breaking changes may occur before stable 1.0. The maker recommends it for small to medium projects because Git-provider API limits and repository size can affect performance; it is not an e-commerce platform.
