Case Study: OneSignal streamlines feature flag management and safer rollouts with ConfigCat

OneSignal streamlines feature flag management across 13,500 Kubernetes pods with ConfigCat

OneSignal, an intelligent messaging platform, faced challenges with fragmented feature flag management across its hundreds of backend services and Kubernetes pods. Different teams used a mix of open-source tools and custom in-house solutions, leading to inconsistent processes, limited visibility, and increased deployment risk. To achieve centralized control and safer rollouts, OneSignal adopted the ConfigCat feature flag service.

By implementing ConfigCat, OneSignal consolidated all feature flag management into a single system. The solution provided broad SDK support for their polyglot environment and tools like the ConfigCat Proxy to improve performance and reliability. This enabled both engineering and product teams to conduct controlled, percentage-based rollouts and target features to different customer cohorts, significantly reducing deployment risk and increasing release confidence across their large-scale infrastructure.
