I just couldn't find anything to perform simple monitoring on any kind of server, vm or container, that didn't come with crazy overkill on stats etc, or setup so complex that it made your eyes burn, and price tags that would afford a nice house.
With over 20 servers to monitor, it was getting too much to keep an eye on.
So, I built ServerUP - https://www.serverup.cloud
Cheap, effective, does exactly what it says on the tin - or website in this case.
Super nice and simple. I like it! I've been using UptimeRobot, but maybe I'll switch ;)
Thanks for the feedback :) You'd be most welcome!
