Minecraft 1.20.1, 1.21.1用Fabric API MOD

Install Millida Launcher

The launcher is free: download it at millida.net/launcher and sign in with any nickname.

Click “Install” on this page

The launcher opens and installs the mod for Minecraft 1.16–26.3 on Fabric automatically.

Launch the game

A profile with it appears in the launcher: click “Play”.

Install Fabric

The loader must match the game version of the mod file, for example Minecraft 26.3. After installing it, a separate profile appears in your launcher.

Download the file for your version

In the version list above, pick the file fabric-api-0.165.0+26.3.jar (1.7 MB) for your game version.

Put it in the mods folder

The folder is inside .minecraft (Windows: %appdata%\.minecraft\mods). If it does not exist, create it.

Launch the loader profile

Open “Mods” in the main menu: Fabric API should be in the list.

A server on Fabric

The mod only works on a server with the same loader and game version, for example 26.3.

File goes into the server’s mods folder

Stop the server, put the mod file into the mods folder and start the server again.

Use the “To server” button

On Millida Hosting, the button at the top of the page uploads the file to your server and restarts it for you.
