Amplitude

Amplitude is a product-analytics platform built for teams practicing product-led growth. Where a tool like Google Analytics centers on web traffic and marketing, Amplitude centers on in-product behavior — which features people use, where they drop off in a funnel, how cohorts retain, and what paths lead to conversion. It competes most directly with Mixpanel and Heap, and is used by a wide range of product companies to decide what to build next.

Its AI layer sits on top of that behavioral data. Amplitude AI lets you ask questions in plain English instead of manually building charts, predictive features can score which users are likely to convert or churn, and the platform surfaces automated insights and anomalies. Over the years Amplitude has expanded from analytics into an adjacent suite: Experiment (A/B testing and feature flags), a Customer Data Platform, and Session Replay for watching real sessions — so behavioral data, testing, and qualitative playback live together.

Key Features

• Behavioral analytics: funnels, retention, segmentation, pathfinder
• Amplitude AI for natural-language data exploration
• Predictive cohorts for conversion and churn scoring
• Experiment — A/B testing and feature-flag management
• Session Replay for qualitative session review
• Built-in Customer Data Platform for governed event data

Pricing

• Free (Starter): Core analytics with a monthly tracked-user cap
• Plus (~$49+/month): Higher limits and advanced charts for growing teams
• Growth / Enterprise: Custom pricing with governance, SSO, and dedicated support

Pricing scales with monthly tracked users, so costs grow with your audience.

Best For

Product managers, growth teams, and data analysts at product-led companies who need serious behavioral analytics, experimentation, and predictive insight in one place.

Limitations

The pricing model is tied to tracked-user volume, so bills can rise fast as you grow, and the free tier’s caps arrive quickly for a busy product. The platform is deep enough to require onboarding and instrumentation discipline to use well. For a small app that just needs basic metrics, Amplitude is more than you need — a lighter tool like Mixpanel’s free tier or plain GA4 may be the better starting point.
