j4mc

j4mc lets you open your singleplayer world to friends without port forwarding.

Open your world to LAN, wait a moment, and j4mc gives you a public *.j4m.uk address that your friends can join through.

Features

How It Works

  1. Install j4mc.
  2. Open a singleplayer world.
  3. Click Open to LAN.
  4. Wait for j4mc to assign an address.
  5. Send the ip address to your friends.

Remote server disclosure

j4mc connects to the j4m.uk relay backend when you open a singleplayer world to LAN. The relay assigns a public *.j4m.uk address and forwards Minecraft TCP traffic between your LAN world and players joining through that address.

The relay may process the requested hostname, LAN port, Minecraft account name provided by the client, connection metadata, and tunnel traffic needed to route the connection. The tunnel closes when the LAN world is closed or the client disconnects.
