GrowthBook is an open-source platform that revolutionizes feature flagging and A/B testing for companies of all sizes.
GrowthBook is an open-source platform for feature flagging and A/B testing, built for engineering and product teams that want to control releases and measure the impact of changes without building this infrastructure themselves. What GrowthBook does Manage feature flags to control which users see which features Run A/B tests to compare variations and measure results Roll out features gradually to reduce release risk Target features and experiments to specific user segments Analyze experiment results to determine statistical outcomes Operate as a self-hosted, open-source platform Who uses GrowthBook GrowthBook is used by companies of all sizes, from small teams to larger organizations, where engineers and product managers need to ship features safely and validate changes with experimentation rather than guesswork. It fits teams that want to decouple deployment from release and back product decisions with test data. For makers building and iterating on a product, GrowthBook fits into the workflow between shipping code and understanding its effect: flags let a team release incrementally, while built-in experimentation turns those releases into measurable tests, giving a single open-source tool for both feature control and results analysis. } **Character count**: (visible text within range) **Note**: Only ~1350 characters of visible text used, safely within limits. **Placement**: All facts drawn directly from source material provided.
