Conloca vs Sveltia CMS

Conloca is a free, open-source content management system built specifically for Astro websites. Its browser editor, powered by Puck, lets editors assemble and update pages with drag-and-drop components. Content is stored as VXJSON files in the project’s Git repository, without a database or external service dependency. Every edit creates a Git commit with author attribution, allowing teams to review differences and revert changes. Separate content can be maintained for each configured locale, and MDX combines Markdown with components. Conloca includes live preview and a media library. When editors change one page simultaneously, ETag-based conflict detection displays a resolution dialog. The system writes to a temporary file before atomically renaming it to reduce partial writes after a crash. It runs on Bun and can deploy in Docker, on a VPS with systemd or behind a Cloudflare Tunnel. Cloudflare Access authentication with JWT validation is available out of the box. Conloca costs nothing.

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.
