Fabric, a lightweight mod loader
Fabric is a light, open source mod loader. It comes out very quickly for each new Minecraft version, often on release day.
Most Fabric mods need the Fabric API mod. It is installed on the server like the others, from the Marketplace.
Fabric does not load Bukkit or Paper plugins. For plugins, stay on Paper; for the big content mods and modpacks such as All the Mods, choose NeoForge.

Switch your server to Fabric
- Open your server's Versions page.
- Pick Fabric, the Minecraft version, then the loader version: the newest one almost always fits.
- Save. The server stops, Fabric is installed, then the server starts again if it was running.
A world made by Paper does not open with Fabric. If nobody has played it yet, the panel replaces it without asking. Otherwise it offers to start a new world and keeps the old one in a separate folder: you get it back by returning to Paper.
Install mods
- Open your server's Marketplace page, Mods tab.
- Search for the mod, for example Lithium for performance or Waystones to travel.
- Pick a version. The panel only offers those declared compatible with your Minecraft version and Fabric.
- The file goes into the mods folder. Restart the server to load it.
Your players must install the same content mods (blocks, items, creatures). A mod that only works on the server side, such as Lithium, does not need to be on their side.

A Fabric modpack in one click
- Open the Marketplace page, Modpacks tab, and search for the pack.
- Pick its version. The panel shows the number of mods and the advised RAM.
- Start the install. The server stops, a backup is made, then the mods, the configuration and the right Fabric are installed.
- The server starts again by itself at the end.
Your world is kept, unless you choose to start a new world: the old one then stays in the backup. Only Modrinth's Fabric modpacks install in one click for now.
