Feature Delivery & Experimentation platforms enable Product teams to run controlled rollouts, feature flags, and A/B tests that measure user impact before committing to full releases. Core capabilities include feature flag management with targeting rules, percentage-based and audience-based rollouts, experimentation frameworks with statistical significance calculation, kill switches for instant rollback, multi-variate testing, event-based metric tracking, and integration with CI/CD, product analytics, and data warehouse systems. The category spans feature management platforms (LaunchDarkly, Split, Statsig, Eppo, GrowthBook) and experimentation modules within broader product analytics suites (Amplitude Experiment, Optimizely Feature Experimentation).
