## What is Sveltia CMS?

4. **Framework-Agnostic**
   - Served as vanilla JavaScript bundle
   - Works with Hugo, Jekyll, 11ty, Gatsby, Astro, Next.js, SvelteKit
   - No React, Vue, or framework runtime dependencies
   - Compatible with any static site generator

5. **First-Class Internationalization**
   - Multiple language support built-in
   - One-click DeepL translation integration
   - Locale switching while editing
   - Flexible i18n structures (files, folders, single file)
