PostHog vs Amplitude for Shopify Hydrogen: Headless Analytics Compared (2026)
Most Shopify Hydrogen storefronts ship analytics late and ship it wrong. Pixel based tracking breaks under server side rendering, GA4 misses half the conversion events because the cart and checkout live on different domains, and the analytics team ends up rebuilding the funnel after launch. The two product analytics platforms most enterprise headless commerce teams pick between in 2026 are PostHog and Amplitude. They solve overlapping problems with very different commercial and technical models, and the right choice is workload dependent.
