Verdict
PostHog replaces GA4 plus several other tools by combining analytics, session replay, feature flags, and A/B testing in one platform. GA4 is free and integrates with Google Ads, but PostHog is far more powerful for product-led teams.
Best for: Product engineering teams who want analytics, feature flags, and session replay in one platform
