Great service I have put all my sites on Uptime, perfect notification system for when a site goes down. I changed my older slower host to a better host after I came to know how much the sites were going down from Uptime. 100% recommend if you have sites that earn $$ and can not afford to go down.

Good tools Good tools, responsive support, seems to still be maturing as some basic functionality available in competing services is not available.

Great service Great service, one of the simplest to use in this product space, good integrations for notifications with slack, would love to see some integration with selenium.

Uptime works just fine Uptime works just fine Previously used a more expensive service called Alertbot, happy we made the switch, this is better and less expensive.

Website Life Saver We use Uptime.com to monitor TorontoRentals.com and it gives us peace of mind knowing the second we have any site connectivity issues Uptime will send a text message to us. This happened earlier this year after business hours. I received an Uptime notification that some of our main city URLs went down, I quickly called one of our developers to troubleshoot the server issue and within minutes we had our city URLs back online rendering properly. Without Uptime we would have caught the issue the following morning causing a lot of site visitors to land on 404 urls.
