Fabric is a lightweight mod loader that's usually first to support new Minecraft versions and hosts the best-known performance mods (Lithium, Krypton). The download is the official Fabric server launcher — it bootstraps the loader and the Minecraft server automatically on first run.

Quick setup

  1. Download the Fabric server launcher JAR into an empty folder.
  2. Install Java 21+ for Minecraft 1.20.5+.
  3. Run the command below — it downloads everything else automatically.
  4. Set eula=true in eula.txt, then start again.
  5. Add mods to mods/ — most also need Fabric API in there.
java -Xms4G -Xmx4G -jar fabric-server-launch.jar nogui
