A/B testing platforms: AI Picks

1 niches- tools tracked5 live prompts

A/B testing and experimentation platforms run the controlled experiments behind product, pricing, and growth decisions. The category has merged with feature flags: most modern picks ship both as one platform. AI assistants now recommend Statsig, PostHog, and GrowthBook far more often than Optimizely or VWO when the buyer mentions SaaS or product-led growth context.
