Quick Setup (< 1 hour)

You can use GrowthBook to run feature flags and A/B tests directly connected to your data warehouse. It lets you release features gradually, test changes with real users, and measure results using your existing data. You can create experiments without engineering help, control feature rollouts, and analyze performance with Bayesian or Frequentist statistics. The platform includes visual editing for website tests and connects with common event tracking systems.
