I am part of the amazing team behind PaperMC. We create an Open Source modification of the vanilla server software for the game Minecraft, focused on improving performance, fixing gameplay inconsistencies and bugs and introducing new APIs for plugin developers to use.

I created a MiniMessage when Minecraft introduced a new rich text format that allowed hoverable and clickable messages. It allows developers and users alike to create beatiful messages for their users.

Also check out the WebViewer.

Hangar is PaperMC's upcoming plugin repository, allowing developers to distribute their Paper, Velocity and Waterfall plugin with ease.
