Which to pick
- Pick Amplitude when
- A growth or product team in a scaling software company wants self-serve behavioural analytics and experiments in one place.
- Pick PostHog when
- You build a web or mobile product and want analytics, replay and feature flags in one tool instead of stitching Mixpanel, Hotjar and LaunchDarkly together.
Side by side
Product analytics for funnels, retention and behaviour cohorts, with experiments, session replay and feature flags in the same suite.
A product analytics suite covering event analytics, web analytics, session replay, feature flags, A/B experiments, error tracking, logs and a data warehouse.
Paid tiers get expensive at scale, and like Mixpanel it needs disciplined event tracking to be useful.
Self-hosting is supported only as a hobby deployment and most teams use the paid cloud, where usage-based bills can grow quickly with event volume.
