Outstatic vs Sveltia CMS

Outstatic is a Markdown-focused content management system for websites. Its editor works with Markdown and MDX files in GitHub repositories, where content is stored without a separate database or server. Content is arranged into Collections, Documents, and Singletons; Singletons can hold unique items such as a homepage or site settings. The editor lists custom fields and AI completion. The homepage names support for Docsify, VuePress, MkDocs, SvelteKit, Next.js, Hugo, Docusaurus, Nuxt, Astro, Hexo, Eleventy, VitePress, Zola, Nextra, Fumadocs, Markdoc, and Contentlayer. Outstatic supports self-hosting and a hosted PRO dashboard. GitHub login is documented through OAuth applications or GitHub Apps; PRO adds Google and email sign-in. A PRO project API key can bring AI completion, member management, added login options, automatic content setup, and a managed GitHub relay to a self-hosted instance. The free plan is free; PRO is $9.99 a month, billed $9.99/user/mo. Eligible new PRO subscriptions include a 14-day trial.

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.
