Pendo's free tier supports up to 500 monthly active users and includes product analytics, in-app guides, NPS, and roadmaps, making it a functional starting point. Pendo's paid plans remove the MAU cap with custom limits, add integrations, and unlock session replay, product discovery, Pro edition in-app guides, and data sync at higher tiers. G2 reviewers note that session replay is among the most valued features yet requires a paid upgrade, and that integrations with tools like Salesforce and Zendesk carry additional costs. One G2 reviewer specifically flagged that free-tier metadata limitations created unreliable segmentation data for accounts that stop logging in.
