About GrowthBook
Open source feature flagging and A/B testing platform for engineering and product teams.
GrowthBook lets you roll out features with flags and run controlled experiments (A/B tests) against your existing event tracking tools like GA, Segment, or Mixpanel. Feature evaluation happens locally without additional HTTP requests, which avoids the flickering common in client-side experimentation tools. It supports browser and Node.js environments and includes a Visual Editor for running experiments without writing code.
Where to start
Install the JavaScript SDK, create a GrowthBook instance with your API host and client key, then call `isOn` or `getFeatureValue` to evaluate flags and experiments against user attributes you define.
