PostHog is an open-source, all-in-one product platform, event tracking, session recordings, feature flags, A/B testing and surveys in one system, self-hostable or cloud, billed on raw usage (events/recordings/flags) rather than monthly tracked users.
Free: 1M events + 5K session recordings + 1M feature flag requests/month. Pay-as-you-go beyond that: from $0.00005/event down to $0.000009/event at 250M+ events (steep volume discounts). Self-hosting is also free but requires managing your own infrastructure.
Engineering-led product teams who want one consolidated tool (analytics + flags + experiments + surveys) instead of stitching together separate point solutions, especially those open to self-hosting.
Usage-based pricing (events, not MTUs) means cost scales differently than competitors like Amplitude or Mixpanel: model actual event volume (not merely user count) before comparing pricing across platforms.
