Multilingual Content
Sveltia CMS was born to manage multilingual sites. Edit languages side by side, translate a whole entry with one click, and store content in the structure your framework expects.
Editing
Open any locale in the second pane to translate field by field, or switch it back to the live preview. The language switcher flags missing translations and errors, and a Copy button brings content over from another language.

AI translation
Connect Google Cloud Translation or an LLM from Anthropic, DeepSeek, Google, Mistral AI or OpenAI with your own API key, then translate all fields or just one. Text you mark as excluded stays untouched.

Keep all locales in one file, or use a file or folder per locale. Nested collections and page bundles are supported too, so Sveltia CMS fits Astro, Hugo, Eleventy and other frameworks.
