Recently I have been putting a lot of work into this: https://github.com/Aberdeener/VaultDatabase. It is a web app that links to my Minecraft server and displays statistics and information from in-game and supports things such as uploading schematics to paste in-game (only when logged in!).
I wanted to post it here to get feedback. My good friend @Minenash has been giving me ideas for a while.
Hope you are all well
