Amplitude is a product analytics platform for tracking user behavior through events and funnels, best suited to product and growth teams that need to answer "what are users actually doing in the product" rather than pure marketing-site traffic questions.
What it does
A closer look at Amplitude's event tracking and funnels
Amplitude tracks custom events (clicks, feature usage, conversions) and lets teams build funnels, retention curves, and behavioral cohorts to understand product usage over time. Unlike GA4, it's built around user-level event streams rather than page views and sessions, and it's designed to answer specific product questions ("do users who complete onboarding step 3 retain better") rather than serve as general web traffic reporting.
It's used by product managers, growth teams, and data analysts, typically requiring an engineer or a tag-management setup to instrument the events being tracked. It's common at SaaS and app companies where the core product experience, not a marketing funnel, is the thing being measured and improved.
It competes with Mixpanel, Heap, and PostHog in product analytics; independent reviews consistently note that Amplitude's free and self-serve tiers are more usage-limited than competitors like PostHog, and that getting real value requires clean, deliberate event instrumentation rather than the auto-capture some competitors offer.
