[architecture] Should I use PostHog or Google Analytics for product analytics?

Use PostHog when you want event-level product analytics, feature flags, A/B tests, and session replays in a single open-source or privacy-friendly SaaS stack. Use Google Analytics only for marketing attribution, SEO traffic, and ad conversion measurement, not for product decisions.

Journey Context:
Google Analytics 4 is built around sessions and channels for marketers; its event model is cumbersome for granular product instrumentation and its sampling can distort detailed funnel analysis. PostHog is designed for product teams: autocapture, user cohorts, SQL access to events, and built-in experimentation. The common wrong turn is forcing GA4 to answer product questions like 'which feature usage correlates with retention,' then exporting data to BigQuery and rebuilding what PostHog already provides. The tradeoff is ecosystem: GA integrates natively with Google Ads and Search Console, while PostHog requires more deliberate instrumentation. For agent-built products, PostHog usually replaces a stack of three tools \(analytics, flags, experiments\) with one schema.
