CommandBridge connects Velocity and Paper servers using WebSockets.

• Supports Minecraft 1.20.x to 1.21.x (Not for 1.8, not sorry).

• Java 21 only.

• Paper, Folia, Purpur, Bukkit, Spigot, Velocity, Waterfall.

Build with:

git clone https://github.com/objz/CommandBridge.git
cd CommandBridge
./gradlew shadowJar

Installation and configuration guide is here.

Velocity runs the WebSocket server. Paper runs the client. The connection is authenticated using a shared secret (HMAC). Configs are generated on first run. Port and address settings must match. You copy the key manually, yes, on purpose.

Once connected, you’ll see something like:

[INFO] [CommandBridge]: Client authenticated successfully
[INFO] [CommandBridge]: Added connected client: lobby

Architecture is three modules:

• core – WebSocket implementations, util stuff
• velocity – plugin impl + server
• paper – plugin impl + client

Still to come:

• GUI for managing scripts (cause YAML is great, but not that great)
• Multi-Velocity support
• Public API for extensions, message types, etc
