5 Tools Compared

Mixpanel

Weakness: Pricey at scale; event volume billing adds up fast.

Pick if: Consumer apps with clear funnels.

Amplitude

Strength: Behavioural cohorts, pathfinder, enterprise-grade governance.

Weakness: Learning curve; UI can overwhelm new users.

Pick if: Mid-to-large orgs with analytics maturity.

PostHog

Strength: Open source, self-hostable, session replay + feature flags bundled.

Weakness: Less polished than Amplitude for deep slicing.

Pick if: Startups wanting one tool for everything.

Heap

Strength: Autocapture — no event instrumentation needed upfront.

Weakness: Autocapture noise; still need to define meaningful events.

GA4

Strength: Free, ubiquitous, good for marketing attribution.

Weakness: Weak for deep product analytics; sampling issues.

Pick if: Marketing-led teams, early-stage.

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.
