Amplitude vs PostHog — Attribute Category Vocabulary
Taxonomy of attribute categories used to classify comparison data for Amplitude vs PostHog.
Which platform is cheaper for high-volume analytics?
PostHog is significantly cheaper at scale. Amplitude charges $0.0001-0.0002 per event, meaning 100 million monthly events would cost $10,000-20,000 extra. PostHog's cloud plan maxes out at $369/month regardless of event volume, and self-hosted is completely free. For early-stage companies, PostHog's transparent pricing is predictable; for high-volume enterprises, PostHog saves 60-75% on analytics costs.
Can I use PostHog if I need HIPAA compliance?
No, PostHog does not currently offer HIPAA compliance. Amplitude is HIPAA-certified and suitable for healthcare SaaS applications. If HIPAA is required, you must use Amplitude or a dedicated HIPAA-compliant analytics platform. PostHog has no public roadmap for HIPAA certification.
Does PostHog replace my need for other tools?
PostHog replaces analytics, feature flags, session replay, A/B testing, and survey tools in one platform. Amplitude is analytics-only and requires separate integrations for session replay, feature flags, and experimentation. PostHog reduces tool sprawl; Amplitude integrates with a broader ecosystem of best-in-class tools.
Which has better cohort analysis for complex user segments?
Amplitude offers more sophisticated behavioral cohort analysis with 50+ user property combinations, allowing analysis of complex user journeys across 12+ months of history. PostHog's cohort analysis is more basic, suited for standard segment grouping. If cohort depth is critical, Amplitude is superior; PostHog's cohorts are sufficient for most product teams.
What are the hidden costs I should know about?
Amplitude's hidden cost is per-event pricing that scales unpredictably with product growth. PostHog's hidden cost is self-hosting infrastructure (engineering time, server costs, security patches). Amplitude's SQL access requires enterprise tier ($50K+/year). PostHog includes SQL in all paid plans. For compliance, Amplitude's enterprise pricing is opaque; PostHog's is transparent.
