VoxelPort Fabric Mod

Host your Fabric server without port forwarding. Install the mod and share a normal join address with vanilla players. No signup, no Discord, no token to copy — it just works.

Overview

VoxelPort connects a Fabric server or an Open to LAN singleplayer world to VoxelPort-operated relay infrastructure. Your game opens an outbound encrypted WebSocket connection, the relay assigns a public TCP port, and players join that address from vanilla Minecraft.

Players do not need to install the mod.

Requirements

A device token is generated automatically on first launch — nothing to request or paste.

Quick Start

Singleplayer world

1. Install the VoxelPort mod in your Fabric client.
2. Open Minecraft and load your singleplayer world.
3. Use Minecraft's Open to LAN button.
4. Press Open to VoxelPort from the pause menu.
5. Share the copied play.voxelport.in:<assigned-port> address.

Players joining your address do not need the mod.

Dedicated server

1. Install Fabric Loader on your Minecraft server.
2. Put the VoxelPort mod JAR in your server's mods/ folder.
3. Restart the server.
4. Run /voxelport start.
5. Share the address shown by /voxelport address.

Commands

/voxelport start
/voxelport start <port>
/voxelport status
/voxelport address
/voxelport stop

/voxelport start uses the server's configured Minecraft port automatically. Use /voxelport start <port> only when you need to expose a different local port.

The device token is managed for you; /voxelport token <token> still exists as an advanced override.

Configuration

The mod saves server settings at:

config/voxelport/settings.properties

Example config:

server_token=vp_...        # auto-generated; do not share
public_host=play.voxelport.in
server_host=127.0.0.1
max_connections=200
relay_url=wss://relay.voxelport.in

Leave relay_url blank (or wss://relay.voxelport.in) unless you are testing with VoxelPort support.

How It Works

1. The mod opens an outbound WebSocket to the relay.
2. It registers using its auto-generated device token.
3. The relay assigns a public TCP port.
4. Players join play.voxelport.in:<assigned-port> from vanilla Minecraft.
5. Minecraft traffic is bridged through the relay to your Fabric server.

The relay is a bridge, not a game server. Your world, mods, and player data stay on your own server.

Troubleshooting

Status shows disconnected Make sure your host allows outbound HTTPS/WSS traffic to relay.voxelport.in on port 443.

Players cannot join Run /voxelport status or /voxelport address, then make sure players are joining the public address shown there.

Disconnects with compression or packet errors Update to the latest mod release. Server mode buffers fragmented WebSocket frames and serializes relay writes to prevent packet-stream corruption.
