How to Set Up Dynmap on a Minecraft Server

Dynmap renders your world into a map you can open in a browser, with players shown live.

1. Add a port for the map

Dynmap runs its own small web server, which needs a port.

1. Open Network and click Add Allocation. Note the new port.

2. Install Dynmap

Dynmap works on Paper, Fabric and Forge.

1. In Package Manager, click Browse packages, search for Dynmap, and install it.
2. Package changes are queued and applied the next time the server starts, so restart it from Console when you're done.
3. Stop the server once it has started.

3. Set the port

1. In Files, open plugins/dynmap/configuration.txt (Fabric/Forge: dynmap/configuration.txt).
2. Find webserver-port and set it to the port you added.
3. Save and start the server.

4. Open the map

Go to http://<your server's IP>:<the port> in a browser. Use the IP shown on Network, not a domain name.

The map fills in as players explore. To render everything at once, run:

dynmap fullrender world

This uses a lot of CPU; run it when few players are online.
