Uptime Kuma maintainer here. The reason why I made this because I have some services like databases and websites cannot be down for a long time. I need someone send a notification to me if they are down.

If you think it is not improving your life, it is probably because you don't have such similar scenario and you probably don't need this indeed.

My point is that it may be not improving your life, but it improves my life at least, or others'. That's just a choice.
