EdgePulse

EdgePulse is a web app + lightweight SDK that measures end-to-end latency where it actually matters: inside real user sessions. Instead of synthetic pings that miss CDN, DNS, TLS, device, and last-mile issues, it captures timing spans (DNS, connect, TLS, TTFB, render, websocket RTT) and correlates them with geography, ISP, device class, and release version. It alerts when latency spikes hit specific cohorts (e.g., Android on a certain carrier) and provides a “blame map” that points to likely causes (origin overload, CDN POP regression, third-party script slowdown, routing anomalies). It’s brutally practical: small teams get a clear answer to “is it us or the network?” without building an observability stack. Expect pushback from incumbents—this wins by being narrower, cheaper, and faster to deploy, not by replacing full APM.
