Feature Comparison

FeatureHeapPostHog
Event Tracking SetupAutomatic capture of all user interactions without any code instrumentation or manual event definition requiredRequires manual event tracking setup and implementation, though provides SDKs and autocapture capabilities
Retroactive AnalysisCore strength - can query and analyze historical data for events that weren't explicitly defined at the time of captureLimited retroactive capabilities - primarily analyzes events that were defined and tracked from implementation forward
Session ReplayOffers session replay and user journey mapping to visualize individual user interactions and pathsProvides comprehensive session recording and replay features with detailed user interaction playback
Experimentation & Feature ManagementFocuses on analytics and attribution modeling rather than experimentation; requires integration with other tools for A/B testingBuilt-in feature flags, A/B testing, and multivariate testing capabilities integrated directly into the platform
Deployment OptionsCloud-only SaaS solution with data hosted on Heap's infrastructureFlexible deployment with both cloud-hosted and self-hosted options for complete data control and privacy compliance
