Filament: Custom Content Tool for Fabric Servers

Filament significantly simplifies the process of adding custom content to Minecraft servers running on the Fabric platform. This tool allows server owners to create new items, blocks, decorative elements, and even mobs using simple JSON files — without the need for programming code. Simply configure the desired block, item, decoration, or armor, and everything is ready for use!

Players can connect to servers with Filament installed without installing additional client mods, as the system uses resource packs, item display entities, and packet-based data transfer methods.

Decorations and other features have minimal impact on server performance due to their packet-oriented architecture.

It is recommended to use Polymer's automatic resource pack hosting feature — no third-party servers required.

In short: An alternative to ItemsAdder/Oraxen for Fabric.
