Amplitude vs Heap

Amplitude Experiment tracks both the primary metric and predefined guardrails in parallel, stopping a winning A/B test if a guardrail metric like session length drops below threshold.

Amplitude's predictive cohorts identify users with high churn probability based on behavioral signals, letting growth teams trigger retention campaigns before the user goes inactive.

Heap Illuminate surfaces behavioral patterns in user data that no one explicitly tracked, revealing user segments defined by actual navigation paths rather than assumed journeys.

Heap ties session replays directly to funnel events, so clicking a conversion step immediately shows replays of users who failed that step without requiring separate tagging in a second tool.
