Open source feature flags and A/B testing platform
GrowthBook is an open-source platform for feature flagging and A/B testing that gives engineering and product teams full control over experimentation. It integrates with your existing data warehouse, supports advanced statistical methods (Bayesian, Frequentist, Sequential), and offers 24+ SDKs for seamless implementation across web and mobile.
Control application behavior remotely with boolean, number, string, and JSON flag types with advanced targeting rules
Run unlimited A/B tests with support for Bayesian, Frequentist, and Sequential statistical engines
Run A/B tests on your website without code changes using a no-code visual editor
Connect directly to your data warehouse (BigQuery, Snowflake, Redshift, etc.) for experiment analysis without data duplication
Incrementally release features to a percentage of users and monitor impact before full deployment
Use CUPED and other advanced statistical techniques to detect smaller effects and run experiments faster
Native SDKs for React, Python, Go, Ruby, Android, iOS, Flutter, and many more platforms
Gradually release new features to increasing percentages of users while monitoring metrics and rolling back instantly if issues arise
Run rigorous A/B tests on pricing pages, onboarding flows, and UI changes with warehouse-native statistical analysis
Decouple code deployment from feature releases using feature flags, enabling trunk-based development and safer releases
Connect to your existing data warehouse to analyze experiment results alongside all your product analytics without moving data
Deploy the open-source edition on your own infrastructure for complete data control and privacy
