vSLS
vSLS is a Velocity plugin that integrates your network with the SLS (Server Launch System).
It allows you to dynamically create and manage server instances directly in game using simple commands. vSLS automatically registers new servers with your Velocity proxy, routes players, and provides a lightweight matchmaking and queue system. Server instances are created and scaled based on demand, ensuring efficient resource usage and fast response times.
