I reviewed all of the software monitoring tools in AppSumo, and I settled on Netumo. I was bit nervous because there were not many reviews and there were a couple comments about it having a really bad UI, but those were from a year ago and the reply promised an update. I am here to tell you I can't imagine what the UI/UX was before but now in 2022 it has gone from an alleged weakness into a verified strength! I LOVE the UI. It is very intuitive and user-friendly. And they have some very welcome advanced features like webhook-enabled notifications and REST endpoint monitoring. This is literally everything I could have even hoped for with some unexpected surprises. I seriously doubt any of the other monitoring software options on AppSumo could be better than this.
