GrowthBook is an open-source platform for feature flags, A/B testing experimentation, and product analytics, deployable via Docker or as a cloud service. It is warehouse-native, connecting to data sources like Snowflake, BigQuery, and Databricks, and offers SDKs for 24+ languages and frameworks.
Use cases
- run A/B tests on my website with a stats engine
- manage feature flags with gradual rollouts and targeting
- self-host a feature flag platform with docker
- run experiments on data in my snowflake or bigquery warehouse
- add feature flags to a react app
- track product analytics and build dashboards
- do split testing without a paid SaaS tool
- integrate feature flag management into my IDE via MCP
When to choose
- you want an open-source, self-hostable alternative to LaunchDarkly or Optimizely
- your experiment data lives in a data warehouse and you want warehouse-native analysis
- you need advanced statistics like CUPED, sequential testing, Bayesian, or bandits
- you need SDKs across many languages including React, Python, Android, and iOS
- you want feature flags, experimentation, and product analytics in one platform
When to avoid
- you only need a tiny client-side toggle library with no management UI
- you want a fully managed SaaS with zero infrastructure and no cloud dependency
- your team has no data warehouse and you don't want to rely on their managed warehouse
- you need a permissively licensed dependency to embed in a commercial product (license is custom)
