Web Analytics · Updated 2026
Quick Verdict
Choose Google Analytics for a free, industry-standard solution focused on marketing and traffic reporting. Choose PostHog for engineering-led teams needing integrated product analytics, privacy compliance, and data ownership from an open-source platform.
Google Analytics is a dominant, free SaaS tool for tracking website traffic and user acquisition, offering unmatched market share and a vast ecosystem. PostHog is an open-source product analytics platform that combines analytics with session replay, feature flags, and surveys in one suite, emphasizing data ownership and privacy. While both have free tiers, Google Analytics operates as a cloud service, whereas PostHog can be self-hosted. Their core divergence is in philosophy: GA is a marketing-centric reporting tool, while PostHog is an integrated, product-led growth platform for building features.

Choose Google Analytics if...
Google Analytics is the better choice for marketing teams, content publishers, and businesses that need a reliable, universally recognized tool for measuring web traffic, acquisition channels, and audience demographics. It's ideal when you want a straightforward, free solution with extensive third-party integrations and documentation, without managing infrastructure.
Choose PostHog if...
PostHog is the superior choice for product teams and developers who want to tightly integrate analytics with product development, using features like session replay, A/B testing, and feature flags. It's essential for organizations with strict data privacy requirements (GDPR, HIPAA) needing self-hosting, or those avoiding third-party data sharing inherent in traditional SaaS analytics.
