Amplitude vs Heap

Pick Amplitude if you run a product with enough users that behaviour is the real question, and someone owns the tracking plan. You get funnels, cohorts and segments, plus session replay, heatmaps, experiments, guides and surveys under one roof. The free plan has no time limit, every plan has unlimited seats, and the MCP server works on the free plan too. Expect a learning curve and dense screens. Usage-based pricing grows with event volume, so estimate yours first. Start with one funnel and one retention question. The vendor also runs a programme that gives early-stage companies a free year of a paid plan.

Pick Heap if you want behaviour data fast and cannot plan every event in advance. One snippet captures every interaction, and you apply new definitions to history, so the question you think of next quarter can still be answered. It adds session replay, heatmaps, maps of user flows and a chat assistant, and it suits product, marketing and data people who do not write SQL. Name events clearly and agree who owns them, or the reports multiply and nobody trusts them. Mask sensitive fields and respect consent. Paid plans are priced by session volume, and Heap is now part of Contentsquare.
