GrowthBook offers an open-source platform for A/B testing, allowing companies to compare two versions of a webpage or app to determine which performs better. The platform integrates with existing data sources, enabling teams to conduct their own tests without needing to create a custom solution. It is particularly useful for product, engineering, and marketing teams that focus on data-driven decision-making, helping them test hypotheses and optimize digital products. Unlike competitors, GrowthBook's open-source model allows users to start for free and scale up to premium features and support as needed. The company's goal is to empower organizations to continuously experiment and improve their offerings through accessible A/B testing.
