Amplitude vs Google Analytics

Amplitude is a digital analytics platform from San Francisco, founded in 2012 by Spenser Skates, Curtis Liu and Jeffrey Wang and listed on Nasdaq (AMPL) since its 2021 direct listing. It started as event-based product analytics for mobile apps and now helps product, growth and marketing teams see how people use their apps and websites and what drives conversion and retention.

The platform combines product and web analytics (funnels, retention, cohorts, journeys), session replay and heatmaps, feature flags and A/B testing, in-app guides and surveys (from the 2024 Command AI acquisition) and audience syncing to ad and messaging tools. AI agents can monitor dashboards, explain metric changes and answer questions, and an MCP server exposes Amplitude data to AI tools. Free covers 2 million events a month; Plus is usage-based; Growth and Enterprise are custom-priced through sales.

It fits product-led companies that need self-serve analysis for non-technical teams. Mixpanel is the closest rival with simpler pricing; PostHog is cheaper and open source with an engineering focus; Pendo is stronger on in-app guidance for B2B software; Google Analytics is free but built for marketing attribution.

In July 2026 Amplitude dropped the fixed 49 dollar Plus tier based on monthly tracked users for event-based pricing from 0 dollars, and the Free plan now includes session replay, guides and AI agents. Startups with under 20 employees and under 10 million dollars raised can apply for a free year of Growth.

Google Analytics 4 is Google's free, event-based analytics platform, which replaced Universal Analytics in July 2023. Every interaction, from page views to purchases, is recorded as an event with parameters, and web and mobile app data can be measured together in one property. It remains the most widely installed analytics tool on the web, largely because it is free and tightly connected to Google's advertising products.

GA4 offers standard reports for acquisition, engagement, monetisation and retention, explorations for funnels, paths, segments and cohorts, machine learning features such as predictive audiences and anomaly detection, and modelled conversions that fill gaps when cookies are refused. Native integrations with Google Ads, Search Console, Merchant Center and BigQuery support attribution, bidding and free export of raw events for analysis. Google Tag Manager is commonly used to set up tracking. The enterprise version, Google Analytics 360, adds higher limits, unsampled data, SLAs and support for a substantial annual fee.

GA4 is indispensable for businesses that advertise on Google and want conversion data flowing into campaigns. Its weaknesses are a steep learning curve, data thresholds that hide small segments, and privacy requirements: in the EU and under similar laws, consent must be collected and Consent Mode implemented, or data is lost. Plausible, Fathom and Umami are simpler cookie-free alternatives for content sites, Matomo offers self-hosting and data ownership, and Mixpanel or Amplitude are better for product analytics.
