What is STACKIT CDN?
STACKIT CDN is a Content Delivery Network that has been generally available (GA) since December 2025. The service delivers content with regional control: geo-fencing lets you define which regions (Europe, North America, Asia, Africa) cache and deliver your content, while origin data can be hosted in German data centers. Since April 2026, an Image Optimizer add-on is also available for automatic image optimization.
