Yottaa Real User Monitoring
Yottaa Real User Monitoring is a performance monitoring service for eCommerce and digital commerce teams. Its Hybrid RUM combines browser, edge, and origin data to show where issues begin and how they affect shopper journeys. It connects frontend behavior, CDN delivery, and backend response time across the delivery path. Core Web Vitals—LCP, INP, and CLS—can be broken down by page, element, and path. Single-page applications receive route-level soft-navigation metrics. Anomaly AI surfaces unexpected performance degradations. Yottaa says it captures 100% of traffic, including sessions browser-only tools may miss when beacons are blocked or sessions fail. Native integrations include GA4, Adobe Analytics, and Shopify Analytics. Performance data is available through REST APIs and an MCP server for compatible clients including Claude Code, Cursor, Claude Desktop, and VS Code. Implementation uses one client-side tag plus Fastly real-time log streaming. The free diagnostics plan costs nothing and requires no credit card.
