I like that it offers a free way to check that your website is up from outside of my network and whitelisted IP addresses. Once setup, I don't have to do anything and it will notify me if and when it goes down. Then again once it's up. This way I don't freak out if I see the email late and didn't catch it on when it went down. The free plan does pretty much everything a single website owner could ask for. If you have many sites to check then you'll have to upgrade but I found it cheaper than most of the other solutions available.

It is a good value in comparison with some more advanced tools that include similar features. It also is fairly easy to get the hang of and seutp.

I like how UptimeRobot alerts us whenever there is an issue, helping us feel more secure about our website's health. I'm able to know the exact moments our websites have issues so we can resolve them quickly. It's somewhat simple to set up.
