multiconnect

Mod Capabilities

This mod enables a Minecraft client on the latest game version to connect to servers running older versions (as well as servers on the current version).

Currently supports connections to versions up to 1.11 (stable support) and 1.8 (experimental support). Requires Fabric-loader to function.

How is multiconnect different from other solutions?

The main difference between multiconnect and similar projects like ViaVersion and ProtocolSupport is that it's a client-side solution. This key advantage allows fixing many version differences directly on the client side - problems that cannot be resolved on the server. At the time of writing, multiconnect is the only mod that corrects swimming mechanics from version 1.12, parkour differences, and restores removed features such as command syntax on the client.

On the other hand, multiconnect only supports the latest Minecraft client version and works exclusively on Fabric. It also doesn't yet cover as many versions as ViaVersion and ProtocolSupport.

Using with ViaFabric

If you need to connect to servers older than what multiconnect currently supports, you can install ViaFabric alongside multiconnect - these two mods are compatible. Multiconnect will handle everything it can, and ViaFabric will complete the connection. Detailed setup instructions can be found in the ViaFabric documentation.
