Pros

  • Unlimited seats on all plans
  • Free tier is generous: 1M events, 5K session replays, 1M feature flag requests/month
  • Native A/B testing + feature flags on all plans
  • Open-source and self-hostable
  • SQL access (HogQL)

Cons

  • UI is clunky and developer-oriented
  • Mobile session replay is limited and cost more
  • Setup complexity is real
  • Autocapture eats your free tier fast with low-value events
  • No in-app engagement layer
  • Query speed degrades on complex reports at scale

Summary

PostHog is the most cost-efficient all-in-one analytics stack available. The breadth (analytics + replay + feature flags + experiments + surveys + data warehouse) for essentially free up to ~10K MAU is great value, and really hard to argue against for indie and early-scale stage.
