CatServer
CatServer is a high-performance server core designed for Forge, Bukkit, and Spigot, enabling strong optimization and wide compatibility with most mods and plugins. Originally part of the LoliServer project, it now functions as a maintained branch offering enhanced optimization and compatibility. The latest version, supporting Minecraft 1.16.5, is available on the official build site. Featuring original and Paper optimizations, CatServer boosts server performance, supports plugin and virtual player compatibility, and addresses vanilla security issues. It includes configurable options and APIs for mod-plugin interaction, with Java 8 or 11 recommended for best compatibility.
