| Feature | Google Analytics | PostHog |
|---|---|---|
| Analytics and Event Tracking | Comprehensive web analytics with automatic pageview tracking, custom event tracking, and extensive demographic and audience segmentation capabilities through Google's vast data network | Product-focused event tracking with unlimited custom events, autocapture of all interactions, and retroactive event definition without needing prior configuration |
| Session Replay | Not available natively; requires third-party integrations like Hotjar or Microsoft Clarity to view user session recordings | Built-in session recording and replay with console logs, network activity, and the ability to watch exactly what users did on your site |
| A/B Testing and Experimentation | Basic A/B testing through Google Optimize integration (now deprecated), primarily relies on Google Ads for experimentation or requires third-party tools | Native A/B testing and multivariate testing with feature flags, allowing developers to test features and variants directly within the platform |
| Data Ownership and Privacy | Data stored on Google's servers with standard privacy controls; increasingly blocked by ad blockers and privacy tools; subject to Google's data policies | Self-hosting option provides complete data ownership and control; cloud version with EU/US hosting options; better compliance with strict privacy regulations like GDPR |
| Marketing Integration | Seamless integration with Google Ads, Search Console, Display Network, and other Google marketing tools; excellent for attribution and campaign tracking | Limited marketing platform integrations; focuses more on product analytics rather than marketing attribution; better suited for product development workflows |
| Learning Curve and Implementation | Complex interface with steep learning curve; extensive documentation and large community; can be overwhelming for beginners but powerful once mastered | Developer-friendly with straightforward implementation; steeper learning curve than simple tools but more intuitive than GA4 for product teams; requires technical knowledge for self-hosting |
Pricing Comparison
Both tools offer generous free tiers at $0/month—Google Analytics is free for most businesses with data sampling at high volumes, while PostHog offers 1 million events free monthly with transparent usage-based pricing beyond that. PostHog can become expensive at enterprise scale with high event volumes, while Google Analytics offers unlimited free usage but may require the paid Analytics 360 ($50k+/year) for enterprise features and unsampled data.
