Filament: Custom Content Adder for Fabric Servers

filament simplifies adding custom content to Fabric-based Minecraft servers. It allows server owners to add new items, blocks, decorations and even mobs using JSON files—no coding required. Configure a block, item, decoration, or armor, and you're ready to go!

Clients can connect to servers using filament without installing any mods, as it relies on a resource pack, item display entities, and packet-based methods.

Decorations and other features have minimal server performance impact due to their packet-based nature.

Use Polymer's auto-hosting capability to host the resource pack—no third-party server required.

TLDR: ItemsAdder/Oraxen alternative for Fabric.
