filament [1.21.5] [1.20.6]

This mod simplifies the process of adding custom content to Fabric-based Minecraft servers. It allows server owners or content creators to add new items, blocks, and decorations without writing a single line of code.

All data is passed through json files, just configure the block, item, decoration, or armor and you’re good to go! Clients connecting to servers using Filament do not need to install any mods, they can connect using regular clients.

This is made possible by the resource pack, item renderers, and other package solutions. Since most features, especially decoration, are package-based, the impact on server performance is very low. To host a resource pack, polymers auto hosting should be used, no third-party server is required!
