About this Modpack

This is a simple fabric modpack to make cross play between bedrock and java possible, it keeps changes to a minimum and pays attention only to server management and optimization, like paper would (but without being intrusive, meaning that the configuration is your job).

The focus is on production updated mods, or at least reliable mods and updates.
Expect tested updates, more or less with all the mods, maybe something removed temporarily sometimes.

Originally made for my own server.

This mod pack can be used on server or client, or be used as base for any other mods.
To use it as server, I recommend docker itzg/minecraft-server
