What GrowthBook is, in short
GrowthBook competes in the product experimentation and feature-management market, spanning warehouse-native A/B testing, feature flags, and lightweight product analytics. It evaluates flags locally through SDKs and analyzes experiment outcomes against customer-managed warehouse data or a managed warehouse, rather than requiring a proprietary behavioral-data store.
