Amplitude is a proprietary product analytics platform for tracking user behavior, funnels, and experimentation, used widely by product teams. Its free Starter plan caps out at 1,000 monthly tracked users, and real-world paid contracts for growing companies commonly run into the tens of thousands of dollars per year based on usage — plus it's closed source, so your product data lives entirely on Amplitude's infrastructure.
If you want product analytics, session replay, and feature flags without usage-based pricing that scales into enterprise contract territory, PostHog is the open-source alternative, self-hostable or usage-priced on your own terms.
