PostHog vs Amplitude
PostHog versus Amplitude is open-core product analytics versus a dedicated analytics cloud. Replay and flags tilt PostHog; enterprise charts tilt Amplitude.
Twin Scores side by side
PostHog
PostHog is product analytics with session replay, feature flags, experiments, and surveys — open-core and self-hostable. Humans live in funnels and replays. Capture APIs, flags, and HogQL give agents a full product-data loop. We like that the company publishes pricing math.
Amplitude
Amplitude is a product analytics cloud used by growth and data teams for funnels, retention, and taxonomy. The chart UI is the human product. Ingestion APIs and the dashboard API serve agents. Heavier than PostHog for teams that want a vendor, not a repo.
