Sveltia CMS
Toronto, Canada
What it is
Sveltia CMS is a free, open-source, Git-based headless content management system for Jamstack development. It runs as a JavaScript application in a browser delivered through a CDN, so it needs no database, server, or build tool. Content can be stored and versioned with GitHub, GitLab, Gitea, or Forgejo. The editor handles Markdown, YAML, JSON, and TOML, and its JavaScript API supports custom fields, previews, and editor components. It includes visual editing, live preview, approval workflow, dark mode, keyboard shortcuts, mobile and tablet support, drag-and-drop uploads, search, and accessibility features. Multilingual projects can use one-click AI translation through Google Cloud Translation, Anthropic, or OpenAI. A digital asset library supports external media, stock-photo services, and WebP conversion. Security documentation covers HTML sanitization, HTTPS-only operation, sandboxed iframes, and Content Security Policy generation. Sveltia is free for personal and commercial use, requires no account or subscription, and is currently in beta.
