"Across the top-reviewed set, the market splits between developer-centric experimentation and no-code conversion tools. PostHog, Statsig, and GrowthBook lead the product-engineering side with feature flags, rollout controls, analytics, and rigorous experiment analysis. Elsewhere, tools skew toward web CRO, funnel personalization, and channel-specific testing for sites, ecommerce, social profiles, and creator workflows."
