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.
