RUM tools capture the experience your real users have, in their browsers, on their devices. This is an honest shortlist for 2026, ordered by depth of front-end insight, OpenTelemetry support, session replay and privacy. Opstral is not a dedicated RUM product, so it is not ranked here; where it fits is noted at the end.

What is the best RUM tool in 2026?
It depends on your stack. Datadog and Dynatrace lead on depth and integration, Grafana Faro for open-source and OpenTelemetry, and Sentry for error-first developer teams. Match the tool to whether you value integration, openness or error focus.
Should a RUM tool support OpenTelemetry?
Increasingly yes. OpenTelemetry browser instrumentation keeps your front-end telemetry portable and lets it flow into the same pipeline as backend traces, avoiding lock-in.
Does Opstral do RUM?
Opstral is not a dedicated RUM product, but it is OpenTelemetry-native and ingests RUM and browser telemetry, correlating it with the backend and adding autonomous resolution on top.
