Google Analytics 4 vs 
Heap (2026 Comparison)
GA4 is free and marketing-first; Heap autocaptures every product interaction retroactively.
Google Analytics 4 is free and excels at web traffic, campaign attribution, and Google Ads reporting, but it requires deliberate event setup and its product-analysis tools are limited. Heap automatically captures every click, form, and pageview so you can analyze behavior retroactively without pre-planning events, at the cost of quote-based pricing that scales with tracked users. Choose GA4 for free marketing analytics; choose Heap for instrumentation-free product analytics.
