What is Real User Monitoring (RUM)?
Real User Monitoring (RUM) captures actual user journeys on your site or app—from navigation timing to CWV such as INP, LCP, and CLS. Unlike lab tests, RUM reflects real devices, networks, geos, and behaviors, making it the gold standard for prioritizing performance work that moves business KPIs.
RUM (Real User Monitoring)
- Measures real traffic: browsers, devices, networks, geos.
- Tracks Core Web Vitals (INP/LCP/CLS) on live pages.
- Surfaces experience outliers (slow countries, ISPs, pages).
- Correlates with conversions, errors, and session context.
Best when you need to prioritize work by business impact and prove improvements.
Synthetic Monitoring
- Runs scripted tests from controlled locations.
- Great for uptime, regression checks, and baselines.
- Validates critical flows (login, checkout) 24/7.
- Complements RUM when traffic is low or episodic.
Best when you need repeatable measurements and proactive alerts.
Key takeaways
- RUM = reality: measures the experience your users actually feel.
- Synthetics = reliability: ensures critical paths work, even when traffic sleeps.
- Use both for coverage + confidence: prioritize with RUM, prevent with synthetics.
How we chose the best Real User Monitoring (RUM) tools
Transparent, repeatable, vendor-agnostic. We scored each solution on the criteria below, with explicit weightings (total = 100%).
Evaluation scope
- Web RUM (JS agent) and, when applicable, mobile SDKs.
- Coverage of Core Web Vitals including INP.
- Correlation with APM/logs/traces for root-cause.
Use cases considered
- E-commerce funnels (PLP → checkout) and SPA routing.
- Global delivery (CDN/ISP/geo variability).
- Frontend teams needing actionable CWV diagnostics.
Exclusions
- Uptime-only tools without real-user telemetry.
- Legacy agents without CWV/INP support.
- Non-maintained open-source forks.
Weighted criteria (100%)
Deep page-level diagnostics, SPA support, field data fidelity.
Link frontend symptoms to backend causes quickly.
Redaction by default, role-based access, secure sharing.
Journeys, API checks, and parity of metrics with RUM.
Ease of rollout (tag/SDK/extension), overhead, versioning.
Public unit pricing (session/pageview) and predictable tiers.
EU hosting options, contractual controls, sovereignty beyond residency.
Setup guides, actionable dashboards, onboarding quality.
What we measured
- Field CWV distributions (p75), INP diagnostics & attribution.
- RUM↔APM correlation paths and time-to-insight.
- Replay safety: masking, consent flows, retention controls.
- Parity between synthetic journeys and real-user deltas.
How to read scores
- Weight reflects buyer importance; not vendor claims.
- We favor evidence over features (dashboards, docs, hands-on).
- Context matters: if EU governance is key, prioritize that 15% bucket.
Last review: October 22, 2025 — We revisit weightings when standards change (e.g., INP replacing FID).

FAQ — Real User Monitoring (RUM)
What’s the difference between RUM and Synthetic Monitoring?
RUM measures the experience of real users on real devices, networks, and locations, while Synthetic Monitoring runs scripted checks from controlled test nodes 24/7 (uptime and regression coverage).
- RUM = reality (business-impact prioritization, field distributions).
- Synthetics = repeatability (proactive alerts, stable baselines).
- They are complementary: use both for coverage + confidence.
Which metrics does RUM track?
Key field metrics include Core Web Vitals—INP, LCP, CLS—plus TTFB, First Contentful Paint, JavaScript errors, resource timing, and long tasks.
What changed with INP replacing FID?
INP (Interaction to Next Paint) replaced FID as the responsiveness vital in March 2024. INP evaluates interaction latency across the whole visit (not just the first input), giving a truer picture of perceived responsiveness.
Does RUM impact SEO and Core Web Vitals?
Indirectly, yes. RUM provides field data (p75) used for Core Web Vitals. Improving INP/LCP/CLS for real users enhances page experience signals and helps prioritize impactful fixes.
Do I need session replay with RUM?
Recommended but optional. Session replay speeds up UX and JS error diagnosis when used with PII masking, consent integration, and sensible retention policies.
How do privacy and GDPR compliance work with RUM?
- Default PII masking with explicit allowlists.
- Integration with your CMP for consent.
- Role-based access and secure sharing.
- EU hosting options, access logs, and a signed DPA.
How much does a RUM tool cost?
Most vendors price by usage (session or pageview). Control spend with sampling, environment filters, and app/domain scoping. Open-source options shift cost to infrastructure and operations.
Are there open-source RUM options?
Yes. Elastic RUM and Grafana Faro are popular. You gain control and customization, in exchange for operating, securing, and maintaining the stack yourself.
Can I deploy RUM without code changes?
Depending on the vendor: a JS tag (typical), mobile SDKs, or a low-friction browser agent/extension for quick pilots and restricted environments.
How do I instrument a SPA (React/Vue/Angular)?
- Enable SPA navigation detection (history/router hooks).
- Upload source maps for readable JS error stacks.
- Validate INP attribution (event targets, handlers, long tasks).
