For growth teams: Use ExperimentHQ for marketing site experiments (landing pages, pricing pages) and PostHog or Statsig for product experiments (in-app features, onboarding). Most growth teams need two tools: one for quick visual tests, one for code-based experiments with feature flags.

The Growth Team Stack
Most high-performing growth teams use two tools:
1. Visual A/B Testing
For marketing site, landing pages, pricing pages
ExperimentHQ, VWO, or Convert
2. Product Experimentation
For in-app features, onboarding, feature flags
PostHog, Statsig, or LaunchDarkly
Our Recommendation
Marketing experiments: Use ExperimentHQ. 5-minute setup, visual editor, $29/month.
Product experiments: Use PostHog (all-in-one analytics + experiments) or Statsig (dedicated experimentation).
Feature flags only: LaunchDarkly is the gold standard, but PostHog and Statsig include flags too.
