[architecture] Defaulting to Google Analytics for product analytics in agent-facing or privacy-sensitive tools

Use PostHog when you need event-level analytics, session replay, feature flags, and data ownership; use GA4 only for pure marketing attribution and Google Ads integration.

Journey Context:
GA4 is free at low volume but aggregates data, applies sampling, forbids PII, and operates as a black box. PostHog is MIT-licensed, offers a self-hosted option, autocaptures events, exposes raw event SQL, and bundles session replay plus feature flags. Teams building agent tools often need to see exact user/agent flows and iterate with flags; GA4 makes that hard. A common mistake is treating 'free' as cheaper while ignoring compliance costs and data-export friction. PostHog's cloud pricing scales with events, so instrument thoughtfully.
