Website Performance MonitoringThat Pays for Itself
Monitor LCP, CLS, INP, and TTFB continuously. Get revenue impact alerts the moment your site slows down — before Google notices or customers leave.
No code required. Add any URL and AuditJet starts monitoring in seconds.
Website performance monitoring, not just speed tests
One-off speed tests like Google PageSpeed Insights and GTmetrix tell you how fast your site is right now. But performance regressions happen between checks — after a deployment, when a third-party script updates, or when traffic patterns shift.
AuditJet runs continuous Lighthouse scans on a schedule, compares each result to your baseline, and fires alerts with revenue impact the moment a metric regresses.

Everything you need in one platform
AuditJet combines synthetic monitoring, Real User Monitoring, capacity testing, and revenue intelligence — so performance is always visible and actionable.
Synthetic Monitoring
Scheduled Lighthouse scans on mobile and desktop using the same methodology as Google PageSpeed Insights.
Revenue Intelligence
Dollar-per-hour revenue impact for every regression, based on your conversion rate and revenue data.
Regression Alerting
Slack, email, and webhook alerts fire within the next scan cycle when any metric crosses your threshold.
AI Diagnostics
Performance Intelligence synthesises all your data into a 2-sentence diagnosis with one concrete fix.
Real User Monitoring
RUM script captures LCP, CLS, INP from real visitors — field data to complement lab results.
Capacity Testing
Burst load testing from 10 to 200 concurrent users to find your site's breaking point before traffic spikes hit.
Every metric that matters
Built for every team that cares about performance
Engineering
Catch performance regressions in every deployment before they reach production at scale. No more surprise CWV drops after a third-party script update.

What is website performance monitoring?
Website performance monitoring is the continuous measurement of a site's speed, stability, and user experience metrics — LCP, CLS, INP, TTFB — on a scheduled basis. Unlike one-off speed tests, monitoring detects regressions as they happen from deployments, third-party scripts, or traffic changes, and alerts teams before issues affect rankings and revenue.
How does AuditJet monitor website performance?
AuditJet runs scheduled Lighthouse analyses on each configured page using mobile CPU throttling and 4G network simulation — the same methodology Google uses for Core Web Vitals. Scans run at configurable intervals. When any metric crosses a threshold, AuditJet fires a Slack, email, or webhook alert with the regression detail and estimated revenue impact.
What is the difference between website performance monitoring and a speed test?
A speed test is a manual, point-in-time measurement. Website performance monitoring is automated and continuous — running on a schedule and alerting on changes. A speed test tells you how fast your site is right now; monitoring tells you when it gets slower and by how much.
Does AuditJet monitor performance on mobile?
Yes. AuditJet uses mobile CPU throttling and 4G network simulation for all synthetic scans — the same conditions Google uses for CrUX field data collection. This ensures lab scores closely match real user experience on mobile devices.
Can AuditJet monitor multiple pages at once?
Yes. AuditJet monitors multiple pages per site, including product pages, checkout flows, landing pages, and blog posts. Each page is scanned independently on its own schedule. Plans scale from 3 pages (free) to unlimited pages.
