+      "Crazy Egg, founded by Neil Patel and Hiten Shah in 2005, pioneered website heatmaps and has since expanded into A/B testing, session recordings, and surveys. It's a well-known tool for visual website optimization — understanding where visitors click, how far they scroll, and which page elements drive engagement. But Crazy Egg is web-only, proprietary, and focused on visual optimization rather than product analytics.",
+      "OpenPanel serves a different but complementary need. Where Crazy Egg helps you optimize individual pages through visual feedback, OpenPanel helps you understand the entire user journey through event-based product analytics. Funnels show you where users drop off in multi-step flows, retention analysis reveals whether they come back, and user profiles let you track individual behavior across sessions.",
+      "The technical differences are significant for growing teams. Crazy Egg is cloud-only with no self-hosting option and charges based on pageviews. OpenPanel is open source under the MIT license, offers full self-hosting via Docker, and supports mobile apps through native SDKs for iOS, Android, and React Native — capabilities Crazy Egg doesn't provide.",
+      "If you need to go beyond heatmaps and understand how users actually flow through your product, especially across both web and mobile platforms, OpenPanel provides the event-based analytics foundation that visual optimization tools like Crazy Egg can't match."
