One of the more interesting pieces of Microsoft software is the Windows Admin Center where it's a web app to configure a Windows Server. Ideally, it was made for core installs where there's no GUI but it's there as a viable web management panel.

The tool from OP and WAC are pretty similar in terms of functionality and usecase. Why would you want this? Well, imagine your team needing to be able to do server functions but you have less technical team members to do it for you, which is very often the case in big places, most people are familiar with the web browser and having a website to do these sorts of actions makes it easier to have things done in one place without a lot of tools like Remote Desktop, SSH, WinRM, etc. configured.
