AuguroAuguro vs UptimeRobot
Both tell you when your site is down. They disagree about what "down" means, and that disagreement is the whole comparison.
Where UptimeRobot is the better answer
UptimeRobot is free for a very long list of endpoints, it has been around since 2010, and if all you need is "did the server answer", it does that well and costs nothing.
Where it leaves you exposed
It watches the response, not the page. A site that returns 200 while rendering a blank screen is green in UptimeRobot for as long as the outage lasts.

Which should you choose
For a server-rendered site with straightforward requirements, UptimeRobot is excellent value. If your front end is JavaScript, it cannot detect the failure mode most likely to take you offline.
One monitor free, permanently. No card required, and nothing to script.
