Your Site Takes 4 Seconds to Load. You're Losing 25% of Visitors.
Every second of load time costs you conversions. Visual Sentinel monitors page speed, Core Web Vitals, and performance regressions continuously — not just when you remember to test.

What Is Website Performance Monitoring?
Website performance monitoring is the continuous measurement of how quickly your web pages load and respond to user requests. It tracks metrics like Time to First Byte (TTFB), total response time, and HTTP status codes over time — revealing performance degradation before it impacts user experience. Slow websites lose visitors: a 1-second delay in page load reduces conversions by up to 7%, and Google uses page speed as a ranking signal for search results. Performance monitoring helps you identify bottlenecks — overloaded servers, slow database queries, unoptimized assets, or CDN misconfigurations — and fix them before they affect your bottom line. Visual Sentinel tracks performance with every check and displays trends in charts, so you can spot regressions and correlate slowdowns with deployments or traffic spikes.
Response Time Tracking
Track HTTP response times with every check. See trends over hours, days, and weeks to spot degradation early.
Slowdown Alerts
Get notified when response times exceed your thresholds. Fix performance issues before users start complaining.
Performance Trends
Historical charts show how your site performance changes over time. Correlate deployments with speed changes.
Detailed Reports
