A lightweight and high performance multi-version Minecraft limbo server.
Currently supporting 1.7.2-1.15.2, work in progress for 1.16+
The goal of this project is to make a high performance and lightweight limbo server, which enables users to hold thousands of players on a single instance. The way this limbo server works is not by running a regular Minecraft server in the background. Instead, it only sends a few packets to players to allow their client to log in. After the player has logged in, keep-alive packets are sent to keep the connection alive.
Feel free to fork and/or use this project however you desire.
A huge thanks to VelocityPowered for their packet utility and id mapping. Without their project this would have been a lot more time consuming. Please check out their amazing project here
