Last9 Real User Monitoring
What it is
Last9 Real User Monitoring captures performance, error, and network telemetry from people using web and mobile apps, then links frontend issues to backend traces. Its five SDKs cover Web, Android, iOS, React Native, and Flutter. Web telemetry includes Core Web Vitals, JavaScript errors, promise rejections, fetch and XHR requests, and single-page app route changes. Mobile SDKs capture launch and screen timings, crashes, and DNS, TCP, TLS, and TTFB network phases; Android also detects ANRs. The SDKs add W3C trace context so frontend requests and backend work can share a distributed trace. Last9 collects diagnostic telemetry without recording rendered DOM, screen video, or visual session replay. Sampling is configurable per session from 0 to 100 percent. Alerts can target error rate, p95 latency, crashes, and ANRs. Last9 lists more than 100 integrations and supports OpenTelemetry workflows, sending spans and logs over OTLP. It says data is encrypted in transit and at rest and advertises enterprise SSO, MFA requirements, role-based access, audit trails, and zero-trust architecture. Pricing is on request; there is no free plan or trial.
