Hourly monitoring
PageSpeed Insights and Lighthouse only run on demand. AuditJet scans your pages continuously and alerts you to regressions before search engines do.
Comparison guide
AuditJet vs competitors: why continuous monitoring wins.
Public audits are useful once, but AuditJet protects your organic traffic with hourly regression alerts, ranking-focused insights, and team-ready reports.
SEO impact focus
We translate performance metrics into ranking risk and conversion impact so teams know what to fix first.
Team-ready reporting
Generate executive and technical reports with one click, instead of exporting raw audit results manually.
| Feature | AuditJet | Generic tools |
|---|---|---|
| Continuous regression detection | Hourly checks plus alerts for regressions on key pages. | One-off audit only, with no ongoing monitoring. |
| SEO risk prioritization | Prioritizes fixes by ranking and conversion risk. | Drills into performance numbers without business context. |
| Competitor benchmarking | See how your performance compares to top rivals. | No comparative business intelligence built in. |
| Revenue impact model | Calculates estimated $/hour lost per metric regression. | Raw scores only — no revenue or business impact estimate. |
| AI-generated fix blueprints | Code-level recommendations for each flagged metric. | Generic suggestions without project or framework context. |
| Real User Monitoring (RUM) | Script-tag RUM captures actual visitor experience data. | Lab data only — no real-user field measurement. |
| Mobile-first scanning | 4G throttling and mobile CPU simulation on every scan. | Desktop-default audits; mobile often optional or absent. |
| Historical data retention | Up to 1 year of scan history with trend charts. | No persistent history — each run is ephemeral. |
| Alert channels | Slack, email, and webhook alerts per threshold breach. | No proactive alerting — manual re-run required. |
| White-label PDF reports | Client-ready branded reports on the AGENCY plan. | Screenshot exports only; no branded client deliverable. |
Built for busy growth teams
AuditJet is designed to keep product, marketing, and engineering aligned on the technical issues that impact SEO and conversions, not just raw speed metrics.

Frequently asked questions about performance monitoring tools
What is the best website performance monitoring tool in 2025?
- The best tool depends on whether you need continuous monitoring or on-demand snapshots. For teams that need hourly regression detection, Slack alerts, and SEO-focused diagnostics tied to real business impact, AuditJet is purpose-built for that workflow. Public tools like Google PageSpeed Insights and GTmetrix provide one-off snapshots that are useful for spot checks but cannot alert you when a deploy causes an LCP regression at 2 a.m. AuditJet also includes a revenue impact model that estimates the dollar cost per hour of each regression, which no free public tool provides.
How does AuditJet compare to Google PageSpeed Insights?
- Google PageSpeed Insights runs a single on-demand Lighthouse audit and shows field data from the CrUX dataset — it has no scheduling, no alerts, and no historical tracking. AuditJet runs Lighthouse on your pages hourly, stores up to one year of historical scan data, and sends threshold alerts via Slack, email, or webhook when a metric regresses. AuditJet also generates AI fix blueprints with code-level recommendations, whereas PageSpeed Insights shows generic suggestions without project context. For teams managing production sites, AuditJet replaces the manual habit of periodically running PageSpeed Insights with an automated, always-on safety net.
Is AuditJet better than GTmetrix for continuous monitoring?
- GTmetrix offers scheduled monitoring on paid plans but is primarily a waterfall analysis tool focused on individual audits. AuditJet is designed from the ground up for continuous regression detection: it compares every new scan against your historical baseline, fires per-metric threshold alerts, and translates performance scores into SEO ranking risk and estimated revenue impact. AuditJet also includes competitor benchmarking — so you can see whether your LCP of 2.3s is better or worse than the three competitors you care about — which GTmetrix does not offer.
What features should I look for in a performance monitoring tool?
- Look for four core capabilities: (1) continuous automated scanning on a schedule you control, not just on-demand runs; (2) threshold-based alerts sent to the channels your team already uses — Slack, email, or webhook; (3) historical trend data so you can correlate regressions with specific deploys or third-party script changes; and (4) actionable diagnostics rather than raw metric dumps. AuditJet provides all four, and also adds competitor benchmarking, Real User Monitoring via a script tag, mobile-first scanning under 4G throttling, and white-label PDF reports for agency workflows.
Can AuditJet replace my existing speed testing workflow?
- Yes, for most teams. If your current workflow involves manually running PageSpeed Insights or GTmetrix after each release and checking for regressions, AuditJet automates that entirely. Set your LCP, CLS, INP, and Lighthouse score thresholds per page once, and AuditJet handles the rest — scanning hourly, flagging regressions, and routing alerts to your team. For agency workflows, AuditJet's white-label PDF reports replace the manual process of assembling audit screenshots into client-ready documents.
What's the difference between synthetic monitoring and real-user monitoring?
- Synthetic monitoring runs automated browser tests in a controlled lab environment — fixed network speed, fixed device specs — to produce consistent, repeatable measurements. AuditJet's hourly Lighthouse scans are synthetic: they simulate a mobile device on a 4G connection so results are comparable across time. Real User Monitoring (RUM) instruments your actual visitors' browsers and collects performance data from their real devices and real network conditions. AuditJet supports both: synthetic scans catch regressions fast after each deploy, while the AuditJet RUM script tag captures the true distribution of user experience across all your visitors so you can validate that synthetic improvements translate to field improvements.
