GrowthBook is a versatile open-source platform designed for feature flagging and experimentation, aimed at empowering teams to confidently deploy code and assess the effects of product modifications using their own data resources. It allows users to create and manage a variety of feature flags—such as Boolean, number, string, and JSON—while implementing targeting rules, percentage rollouts, safe ramp-ups, and experiment assignments. The platform is optimized for data warehouses, enabling seamless connections to existing data sources like SQL data warehouses, Mixpanel, Google Analytics, and more, facilitating experiments and analyses without transferring raw user-level Personally Identifiable Information (PII) to external services. It offers a flexible approach to usage; teams can choose to utilize solely feature flagging, solely experiment analysis, or integrate both functionalities. Significant features include high-performance lightweight SDKs capable of handling billions of feature lookups daily, a user-friendly visual editor for no-code A/B testing, and comprehensive experiment reporting that employs advanced statistical methods. Additionally, GrowthBook empowers teams to make data-driven decisions with confidence, fostering a culture of experimentation and innovation.
