✓ Use when

Engineering-led orgs that prefer open-source and want experiments computed on their own warehouse data with full control.

✗ Avoid when

Teams without a data warehouse or analytics engineering resources — SaaS-first tools like Statsig are faster to start.

What is GrowthBook?

GrowthBook is an open-source feature flag and experimentation platform that runs experiments against data already in your data warehouse (BigQuery, Snowflake, Postgres, etc.) rather than shipping raw events to a vendor. That architecture keeps PII in your warehouse and reduces costs. Fast-growing among engineering teams that find LaunchDarkly + Amplitude combined prices unjustifiable.
