Crazy Egg vs PostHog

What Crazy Egg is

Crazy Egg records how visitors scroll and click, producing heatmaps and session recordings. Heatmaps answer a specific question — where attention actually goes on a page — that a numbers dashboard cannot. It is a diagnostic tool rather than an analytics system, so it complements rather than replaces traffic reporting.

What PostHog is

PostHog is the 'all-in-one' product analytics suite for developers and modern startups. Unlike Google Analytics, which focuses on traffic, PostHog focuses on user behavior within your product. It combines powerful features like event tracking, session recordings, heatmaps, and feature flags into a single, open-source platform. It allows teams to build better products by understanding exactly how users interact with every feature, and even run A/B tests to see what works best.
