Amplitude

Overview

Amplitude is a digital analytics platform that tracks how real users interact with your website or app. The free Starter plan covers up to 10,000 monthly tracked users and includes product analytics, session replay, A/B testing, and unlimited feature flags. That means a small team can watch recordings of actual user sessions, run experiments on their website with just one line of code, and see which features drive retention, all without paying a cent. The Plus plan starts at $49 per month and scales up to 300,000 monthly tracked users. Amplitude also offers a Startup Scholarship that gives qualifying businesses under 20 employees and under $10 million in funding one free year on the Growth plan. A Forrester study found Amplitude delivered 217% ROI over three years with a six-month payback period.
