GrowthBook

Open-source A/B experimentation + feature flags for data teams.

By GrowthBook, Inc. · Founded 2020 · San Francisco, CA · private

GrowthBook is the open-source feature flag and A/B experimentation platform founded in 2020, with an MIT-licensed core and a Cloud + Enterprise tier on top. Strengths: warehouse-native experimentation that runs SQL queries against your existing data warehouse (BigQuery, Snowflake, Redshift, ClickHouse) instead of duplicating event data, MIT open-source license that is friendlier than BSL, growing GitHub community (8K+ stars), and strong fit for data-team-led organizations. Trade-offs: feature flag governance is lighter than LaunchDarkly, the SaaS UX is functional but less polished than Statsig, and the warehouse-native model assumes you already have a modern data warehouse with quality event data, which is a meaningful prerequisite.

Best for

Data-team-led organizations (20-2,000 employees) already on a modern data warehouse (BigQuery, Snowflake, Redshift, ClickHouse) wanting open-source flags + warehouse-native experimentation.

Worst for

Organizations without a mature data warehouse (Statsig or LaunchDarkly handle event collection), enterprise governance buyers (LaunchDarkly stronger), or pure-flag use cases without experimentation needs (ConfigCat simpler).
