About this Mod
MineTracer
MineTracer is a powerful and lightweight block, container, sign, and kill logging mod for Minecraft servers designed to help server administrators monitor, investigate, and roll back player actions with ease. Built for Fabric, MineTracer provides advanced logging and rollback capabilities while remaining simple to use.
This mod is still under developement so don't expect everything to work flawlessly. Please write an issue report on GitHub if you find a bug, I am happy to recieve feedback!
