Paxi (Forge/NeoForge) is a simple mod for global, automatic data packs and resource packs, so you no longer have to add them to every world by hand. It runs on Forge and NeoForge for Minecraft 1.16 - 26.1.2.
Paxi creates a paxi folder in your config directory: data packs in its datapacks folder load in every world, and resource packs in its resourcepacks folder load when the game starts. Zip files and plain folders both work, and an optional datapack_load_order.json sets the load order – handy for modpack creators.
Building a modpack? Paxi is a one-click install on your Minecraft server from the panel.
