Case Study: Kyivstar achieves scalable, high-performance content delivery for 10 million monthly users with Strapi

Kyivstar uses Strapi for a website and mobile app with 10 million monthly active users

Kyivstar, a leading Ukrainian mobile and fixed Internet operator with about 26 million mobile subscribers and over 1 million fixed broadband users, migrated its main website and My Kyivstar mobile app from Drupal to Strapi (using Strapi Enterprise Edition) to align with its Java/React stack, improve performance, and gain deployment and security flexibility. The move addressed the challenge of replacing a PHP-based CMS that did not fit their tech stack and enabled in-house control over a large, content-heavy site of nearly 6,000 pages.

Strapi provided a headless CMS solution with custom roles, a “proxy setting” collection type to manage phased migrations, and a single Strapi instance with separate environments for web and app content. As a result, Kyivstar migrated ~1,000 high-traffic pages (about 80% of traffic) in nine months, supports ~10 million monthly active users with fast page loads, and enables ~40 staff to create and publish content independently — reducing change cycles from weeks and multiple developers to minutes and a single editor.
