Overview
GrowthBook provides an open-source A/B testing platform that helps product, engineering, and marketing teams run experiments to compare different versions of a webpage or app. The platform works by integrating with a company’s data sources or data warehouse, collecting results from experiments, and offering metrics, statistical analysis, and collaboration tools so teams can decide which variant performs better. The core software is free (open-source), while premium features, enterprise support, and professional services generate revenue. This combination allows organizations to deploy in-house testing without building a custom solution from scratch, while still scaling with advanced analytics and support. GrowthBook’s goal is to help teams make data-driven product decisions through continuous experimentation and optimization.
