GrowthBook

GrowthBook is an open-source experimentation and feature flagging platform that works with your own data warehouse.

Written by Reflective Data experts · updated Oct 5, 2026

It combines feature flags, A/B testing and analysis, and reads experiment data straight from your warehouse, so metrics stay consistent with the rest of your analytics.

It is available as a cloud service or self-hosted, which suits teams with data governance requirements.
