| Feature | Heap | PostHog |
|---|---|---|
| Event Tracking Setup | Automatic capture of all user interactions without any code instrumentation or manual event definition required | Requires manual event tracking setup and implementation, though provides SDKs and autocapture capabilities |
| Retroactive Analysis | Core strength - can query and analyze historical data for events that weren't explicitly defined at the time of capture | Limited retroactive capabilities - primarily analyzes events that were defined and tracked from implementation forward |
| Session Replay | Offers session replay and user journey mapping to visualize individual user interactions and paths | Provides comprehensive session recording and replay features with detailed user interaction playback |
| Experimentation & Feature Management | Focuses on analytics and attribution modeling rather than experimentation; requires integration with other tools for A/B testing | Built-in feature flags, A/B testing, and multivariate testing capabilities integrated directly into the platform |
| Deployment Options | Cloud-only SaaS solution with data hosted on Heap's infrastructure | Flexible deployment with both cloud-hosted and self-hosted options for complete data control and privacy compliance |
| Platform Scope | Dedicated analytics and insights platform with deep focus on user behavior analysis and attribution | All-in-one product operations platform combining analytics, experimentation, and feature management in one tool |
Pricing Comparison
Both tools offer free tiers starting at $0/month, but can become expensive at scale with high event volumes. PostHog provides more transparent pricing and a more generous free tier with 1 million events monthly, while Heap's automatic capture may lead to higher data volumes and costs for large-scale websites.
