What Is Uptime Monitoring?
Uptime monitoring is the practice of continuously checking whether a website or web service is accessible and responding to requests. An uptime monitor sends HTTP requests to your site at regular intervals, typically every 1 to 5 minutes, and alerts you immediately when it detects a failure. This includes HTTP errors (5xx), connection timeouts, DNS resolution failures, and SSL certificate problems. Without uptime monitoring, you rely on customers to report outages, which means lost revenue, damaged trust, and longer recovery times. Visual Sentinel checks your site every 60 seconds from 2 regions (EU + US), verifying not just that your server responds, but that it responds correctly, across 6 monitoring layers including visual regression detection.
What our users say.
“I tried UptimeRobot and ChecklyHQ, but neither solved the problem of finding broken pages until we checked manually. With Visual Sentinel, we get instant alerts and can fix our WordPress sites quickly instead of finding issues by accident.”

“We run an agency and due to Elementor updates or cache issues, some client websites would break. We only found out from client complaints because UptimeRobot didn't catch visual issues. After switching to Visual Sentinel, we get alerts about broken pages in minutes. Would recommend 5/5.”
Jeff QB
The DWCO
“Managing many projects, I can't always keep an eye on every website. When something broke after an update, we wouldn't know until someone reached out. After using Visual Sentinel, life has become a lot easier knowing we'll be alerted via Slack and any team member can jump on it immediately.”
