CDN (Content Delivery Network)

A Content Delivery Network (CDN) is a globally distributed network of servers that delivers your translation files quickly and reliably to users around the world. Using the Locize CDN ensures:

• Fast delivery and low latency, worldwide
• Automatic updates: no need to redeploy your app for translation changes
• High availability and reliability

CDN Types

Locize offers two CDN types: Standard and Pro. Both provide global reach and instant updates, but differ in features and providers.

How to use the CDN

• By default, translations are published to the CDN unless you turn this off in your project settings.
• No need to download translations or redeploy your app for changes to take effect.
• You can choose between Standard and Pro CDN in your Locize project settings.

Private Publishing

Optionally, you can configure publishing to be done in private mode (requires API-Key to access the published translations):

Caching and Performance

• Define a custom Cache-Control max-age value per version to optimize latency.
• For best performance, create a dedicated production version and enable caching on it.
• See latency optimization tips.

Fallback and Hosting Options

• Do I have to use the Locize CDN or can I host / bundle the translations directly?
• I want to use the Locize CDN, but would like to have a fallback that uses local/bundled translations
