Amplitude vs PostHog
A head-to-head comparison of two leading analytics platforms for AI-powered growth. See how they stack up on pricing, performance, and capabilities.
Amplitude
Pricing: Free up to 50K MTU, then custom pricing
Best for: Enterprise teams needing behavioral analytics at scale
PostHog
Pricing: Free up to 1M events/mo, then $0.00031/event
Best for: Engineering-led teams wanting an all-in-one open-source stack
Head-to-Head Comparison
| Criteria | Amplitude | PostHog |
|---|---|---|
| Free Tier Limit | 50K MTU free | 1M events/month cloud; unlimited self-hosted |
| Event Tracking | Manual + warehouse-native ingestion | Manual + autocapture + session recording |
| Built-in Experimentation | Amplitude Experiment — full A/B testing suite | Native A/B testing and feature flags |
| Self-Hosting | Not available | Open-source, fully self-hostable |
| Learning Curve | Steep — powerful but complex enterprise tooling | Moderate — comprehensive but designed for engineering teams |
The Verdict
PostHog and Amplitude both include A/B testing, but their target audiences differ significantly. Amplitude is an enterprise analytics platform designed for large organizations with dedicated data teams and complex behavioral analysis requirements. PostHog is built for engineering-led product teams that want open-source, self-hostable infrastructure with a broad feature set. For startups and engineering-driven companies, PostHog offers more value per dollar (including the free self-hosted tier); for enterprise teams with existing Amplitude contracts and data warehouse integrations, Amplitude's depth is hard to match.
