Why developers love UptimeRobot.

Maciej J., .NET Developer

Effortless monitoring

UptimeRobot has been instrumental in monitoring and maintaining the SLA of my services and websites. Its easy configuration has helped me quickly detect and address availability issues. The mobile app is a standout feature, providing concise summaries and instant push notifications, enabling me to stay on top of any problems, no matter where I am. In summary, UptimeRobot is an essential tool for ensuring optimal online performance.

Brian C., Development Team Lead

Simple, reliable, and saved my bacon at least once!

I've been using Uptime Robot for several years to monitor a side project of mine, and it's always been great at that. At first, I was on the free tier, but I was happy to start paying for usage once it was appropriate. It impressed me a few weeks ago when it caught an SSL certification expiration before it happened. My hosting provider had a defect this year that prevented the cert from auto-renewing like normal. Without UptimeRobot, this would have caused an outage impacting 50,000 users. They didn't have to create this feature, but they did.

Ali K., Full Stack Web, Python & Django Developer

Best server status monitoring service

UptimeRobot is among the services that have conquered my heart. It's great that the free version also provides a lot of possibilities, that it can track the server status very successfully and detect the slightest changes.

Chen C., Web Developer

A must service for every web developer

It's super easy to use, very useful, a priceless service for monitoring your websites! It's pretty great and easy to use.

Thomas S., HubSpot Web Developer

Great product, reasonably priced

It is nice to know that my sites are up and you can't be the pricing. I run several sites for clients and it is a good feeling to know that their sites are up.

Nelson P., Developer

UptimeRobot is 100% effective and great partner!
