ViaProxy

Standalone proxy which uses ViaVersion to translate the protocol between minecraft versions.

ViaProxy allows you to join to essentially any minecraft version server from a modern client.
To download the latest version, go to the Releases section and download the latest version.
Using it is very simple, just run the jar file, and it will start a user interface where everything can be configured.
