Quick Verdict
Choose Amplitude if you are a product or growth team seeking a mature, user-friendly SaaS platform to analyze engagement and conversion. Choose PostHog if you are an engineering-led team that values data ownership, privacy compliance, and wants an open-source, integrated platform you can self-host.
Amplitude is a mature, proprietary SaaS analytics platform focused on providing deep insights into user behavior through an intuitive interface, ideal for non-technical roles. PostHog is an open-source alternative that bundles analytics with session replay, feature flags, and surveys, emphasizing data ownership and privacy. While both offer free tiers, Amplitude's model is cloud-based with usage limits, whereas PostHog can be self-hosted for full control. Their core difference lies in Amplitude's specialized analytics approach versus PostHog's integrated, open-source product suite.
