[architecture] Product analytics: PostHog vs Google Analytics 4

Use PostHog for product-led or engineering teams that need identified user profiles, funnels, feature flags, A/B tests, session replay, and SQL access. Use GA4 for marketing attribution, Google Ads/Search Console integration, and high-traffic content sites where event-level user tracking is unnecessary.

Journey Context:
GA4 is built for web and marketing analytics: traffic sources, conversions, audience demographics, and ad attribution. It is free at most scales but lacks per-user behavior depth, replay, experimentation, and has no EU-only data residency or HIPAA readiness. PostHog is open-source, developer-first, combines product analytics with replay/flags/experiments, and offers EU hosting plus a generous free tier. Don't pay for multiple tools to stitch product data together when PostHog covers the stack; don't abandon Google's marketing ecosystem if your team lives in Google Ads.
