Alternatives to GrowthBook
Open-source feature flagging and A/B testing platform.
GrowthBook ranks #3 of 8 in Feature flag platforms, with an Alt Score of 96. It is licensed under MIT (with GrowthBook Enterprise License for enterprise-only directories), open source with paid hosting from $40/seat/month and available on the web. 13 of 13 checklist rows are verified against a public source.
GrowthBook is an open-source feature flag and experimentation platform with warehouse-native A/B testing; self-hostable or cloud.
Engineering and product teams that want warehouse-native experimentation and feature flags without vendor lock-in, including teams that need to self-host for data-control or compliance reasons.
Open-source feature flags with gradual rollouts and instant kill switches, a full A/B testing and experimentation stats engine (Bayesian/frequentist, CUPED, sequential testing, bandits) that queries your own data warehouse, plus built-in product analytics and 24+ server/client SDKs.
Run GrowthBook as a free self-hosted Docker deployment or on GrowthBook Cloud; SDKs fetch and locally evaluate feature/targeting rules in your app (including at the edge), while experiment results are computed via SQL against your connected warehouse or event tracker rather than routing raw event data through GrowthBook's servers.
