 BlueMap is a tool that generates 3d-maps of your Minecraft worlds and displays them in your browser. Take a look at [this demo](https://bluecolored.de/bluemap). It is really easy to set up - almost plug-and-play - if you use the integrated web-server (optional).
 
-The Sponge/Spigot-Plugin automatically updates your map as soon as something changes in your world, as well as rendering newly generated terrain and managing the render-tasks.
