  • I use UptimeRobot to monitor over 100 endpoints on my site. It's changed my reality from getting people tweeting me that part of my sites are down, to knowing it within 60 seconds and immediately being able to fix it. It's the most simple and easy monitoring app I know and it's made my daily life much easier.

  • We strive for minimal downtime, but if something goes wrong UptimeRobot makes sure that we know about it quickly. We switched to using UptimeRobot years ago as they offered the same services we were getting from a different provider but at a fraction of the cost.


  • I've been using UptimeRobot for years as a cost-effective way to quickly alert me when my sites were down - and when they were back up.
