Open-source feature flags and experimentation that runs on your data warehouse.
GrowthBook stores no event data of its own — it queries your existing warehouse (Snowflake, BigQuery, Redshift, Postgres, ClickHouse) for experiment results, and evaluates flags through lightweight SDKs. It supports both frequentist and Bayesian analysis and can be self-hosted entirely.
