PostHog vs Amplitude
PostHog and Amplitude are increasingly compared as PostHog has grown into a full product intelligence suite. PostHog combines analytics with session replay, feature flags, and A/B testing - all open-source. Amplitude is the established enterprise product analytics leader with deeper behavioral cohort analysis. The choice often depends on whether you want a multi-tool platform or a specialized analytics tool.

Common questions
