PostHog

What is PostHog?

PostHog is a product analytics platform that goes well past pageview counts into understanding how people actually use your product: session replay to watch real user sessions, feature flags for controlled rollouts and A/B testing, and funnel/retention analysis to see where users drop off. It's built for teams that need to answer "why" questions about user behavior, not just "how many people visited," and it bundles what would otherwise be several separate tools (analytics, flags, replay, experimentation) into one platform.

Key features

• Session replay to watch actual recorded user sessions, not just aggregate numbers
• Feature flags and A/B testing built into the same platform as your analytics
• Funnel, retention, and cohort analysis for understanding behavior over time
• Self-hostable open-source option alongside the hosted cloud product
• SQL-based querying (HogQL) for teams that want to go beyond the pre-built reports

Who it's for

The right pick once you've outgrown basic traffic analytics and need to understand actual product usage and behavior, feature flags, and experimentation in one place. If you just want simple, readable pageview and referral data without the added complexity, a lighter tool like Plausible is a better starting point.

Pricing

Usage-based pricing with a generous free tier across its various products (analytics events, replay, flags), scaling up as volume grows. Check the tool's site for current limits and rates.
