Amplitude vs PostHog

Pick Amplitude if your product team lives in cohort analysis and you need an AI that can pull retention curves, funnel drop-offs, and user journey maps without writing SQL. Its 16 tools cover the core analytics workflows—event queries, segmentation, and behavioral cohorts—that product managers actually use daily. Pick PostHog if you want feature flags, session replay, and experimentation wired into the same MCP. PostHog's 50 tools span product analytics, A/B testing, and user session data, making it the better fit for engineering-led teams that run experiments and need the AI to correlate feature rollouts with metric shifts. Buy PostHog if you're consolidating tools and want one MCP for analytics plus experimentation. Buy Amplitude if your org already standardized on it and you just need the AI to surface insights faster. Switching between them after you've built automation is a two-week project—you'll need to remap event taxonomies, rewrite any custom cohort logic, and retrain your team on which tool names to call in prompts.
