GrowthBook

GrowthBook 4.3 is here! It’s time for faster experiments & deeper insights. We're excited to announce post-stratification for experiment analysis. Combined with CUPED, this variance reduction technique lets you run experiments 20%+ faster. Also new in 4.3: 📈 Metric drilldowns let you explore time series, slices, and debug how CUPED/capping affect your numbers, all in one view  🐛 Feature evaluation diagnostics query real SDK events from your data warehouse to troubleshoot targeting issues  📅 Daily participation metrics are a new metric type analogous to DAU (Daily Active Users) but better suited for experimentation New SDKs:  🦀 Rust SDK for performance-critical applications  📺 Roku SDK for smart TV experimentation Plus: result filters, nested saved groups, case-insensitive regex targeting, and dozens of quality-of-life improvements. Thank you to all of our users, contributors, and team for your feedback, ideas, and bug reporting on GitHub and Slack. #Experimentation #FeatureFlags #GrowthBook Learn more below!
