Amplitude review

Amplitude is the broadest documented product analytics package on this list. Its Free plan covers 2M events a month, 10,000 monthly session replays, product and web analytics, AI-powered analysis and limited experiments, guides and surveys, all with unlimited seats and no credit card. Plus starts at $0 for the first 2M events and then bills by event volume up to 70M events, adding custom events and formulas, 20 behavioral cohorts, alerts, heatmaps and 2-year data retention. Growth, on a custom quote, adds conversion drivers, saved metrics, cart analysis, predictions in limited form, 20,000 monthly replays, SSO and project permissions. Enterprise adds data access controls, unlimited projects per portfolio and 50,000 monthly replays. The trade-offs are that Free leaves out behavioral cohorts and custom events, and the higher tiers require a sales conversation. For product teams that want funnels, retention and replay in one tool from day one, it is the strongest documented option.
