Real User Monitoring for WordPress — track actual visitor performance, not synthetic benchmarks.
Synthetic tools like Lighthouse and PageSpeed Insights test from a single location under ideal conditions. Mudrava RUM captures what your real visitors actually experience — across devices, networks, and geographies.
| Synthetic Testing | Mudrava RUM |
|---|---|
| Lab environment | Real user data |
| Single location | Global visitors |
| One device profile | Mobile, tablet, desktop |
| Scheduled snapshots | Every pageview (sampled) |
| Theoretical scores | Actual TTFB, LCP, load times |
- Core Web Vitals — TTFB, LCP, server generation time, total page load
- Zero-config collector — lightweight async JS, no impact on page speed
- Live Monitor dashboard — real-time log with sortable columns and filters
- Performance reports — on-demand modal with averages, P75 LCP, slowest pages
- Email summaries — scheduled daily/weekly via WP-Cron
- Critical TTFB alerts — configurable threshold, consecutive trigger, cooldown
- Smart sampling — 100%, 50%, or 10% traffic sampling rate
- Privacy-first — no PII, no cookies, no external services, all data stays in your DB
- Cache-aware — detects and handles cached page artifacts automatically
- Extensible — action/filter hooks for developers
Screenshots are available on the WordPress.org plugin page.
Live Monitor — filterable real-time performance log with color-coded metrics.
Settings — sampling rate, retention, excluded roles, email reports, TTFB alerts.
Report Modal — aggregated stats, P75 LCP, top slowest pages by LCP.
