PostHog pricing ranges from $0.00005–$0.00005/per event (usage-based), while Amplitude ranges from $0–$49/month. PostHog is typically 100% more affordable, though your actual cost depends on tier and team size.
PostHog and Amplitude are both product analytics platforms, but with different philosophies. PostHog is open-source, self-hostable, and bundles analytics, session recording, feature flags, A/B testing, and heatmaps in one platform. Amplitude is a focused product analytics tool with best-in-class behavioral funnels and cohort analysis.
PostHog’s pricing is usage-based with a generous free tier. Amplitude has a freemium model but charges per tracked user, which can get expensive quickly. Teams choosing between them often weigh PostHog’s bundled feature set against Amplitude’s deeper analytics capabilities.

Our Verdict
Choose PostHog if you want one platform for analytics, session recording, feature flags, and A/B testing. The free tier is generous and the self-hosted option is unmatched for privacy-conscious teams or those on tight budgets.
Choose Amplitude if product analytics is your primary need and you want best-in-class funnel, retention, and cohort analysis. Amplitude’s behavioral analytics are deeper than PostHog’s and its 50K MTU free tier is meaningful for growing products.
