What it is and why it matters

PostHog bundles product analytics, session replay, feature flags, surveys and A/B tests into one project you can run yourself. In the video it is compared with Amplitude and Mixpanel, whose per-event billing can climb sharply as traffic grows. The stated appeal is getting those metrics without paying per event.

Key points

  • Product analytics, session replay, feature flags, surveys and A/B in a single repo
  • Can be self-hosted to avoid per-event billing
  • Funnels, retention curves and heat maps included
