FAQ
Mixpanel or Amplitude in 2026?
Amplitude has pulled ahead for mid-to-large orgs thanks to better governance and behavioural cohorts. Mixpanel remains strong for consumer teams with clear funnel-driven products. At early stage, neither — use PostHog and save the money for when you have enough data to justify the spend.
Is PostHog really good enough to replace Amplitude?
For teams under ~50 product people, yes. Session replay + feature flags + analytics in one tool is a big ergonomic win. For large orgs with strict governance and complex cohort definitions, Amplitude still wins — but PostHog closes the gap every quarter.
