The record

Purpose: Real User Monitoring captures performance, error, and network data from people using web and mobile apps and links issues to backend traces.
SDK coverage: Last9 provides five RUM SDKs: Web, Android, iOS, React Native, and Flutter.
Web telemetry: The web SDK captures Core Web Vitals including LCP, FCP, CLS, INP, and TTFB, plus JavaScript errors, promise rejections, fetch/XHR requests, and SPA route changes.
Mobile telemetry: Mobile SDKs capture launch and screen timings, crashes, and network DNS, TCP, TLS, and TTFB phases; Android also detects ANRs.
Backend correlation: SDKs add W3C trace context in a traceparent header so frontend requests and backend work can share one distributed trace.
No replay: Last9 records diagnostic telemetry without recording the rendered DOM, screen video, or visual session replay.
Sampling: Sampling is configured per session and supports rates from 0 to 100 percent in each SDK.
Pricing model: RUM spans and logs are priced as ingested telemetry under Last9's usage-based model rather than by recorded session.
Alerting: RUM alerts can target error rate, p95 latency, crashes, and ANRs using the same alerting engine as backend telemetry.
Integrations: Last9 lists more than 100 integrations, including Grafana, Kubernetes, PostgreSQL, Datadog, AWS, Azure, New Relic, Google Cloud, Slack, Docker, Prometheus, and MySQL.
OpenTelemetry: Last9 RUM SDKs emit spans and logs over OTLP and use OpenTelemetry-native telemetry workflows.
Security: Last9 states that data is encrypted in transit and at rest and that it provides enterprise SSO, MFA requirements, role-based access, audit trails, and zero-trust architecture.
Compliance: Last9 displays SOC 2, PCI DSS, HIPAA, and ISO 27001 compliance badges.
Support: Last9 advertises 24x7 support from forward-deployed engineers.
