How server versions work

Versions, mods & modpacks · Updated 27 October 2026

Server Versions lets you switch your server type and Minecraft version in a few clicks.

Which type should I pick?

It depends on what you want to add to your server:

  • Just vanilla Minecraft: Vanilla
  • Plugins (EssentialsX, LuckPerms…): Paper or Purpur
  • Mods (Create, JEI…): Fabric, Forge or NeoForge, depending on the mods you use
  • Linking several servers together: Velocity

Mods only work on the loader they were made for.

Change your server version

  1. Open Server Versions in the menu on the left. At the top, you can see what your server is running right now.
  2. Pick the type of server you want, for example Paper.
  3. Choose your Minecraft version. The newest is at the top, or search for a version, like 1.21.
  4. Click Install next to the version you want.
  5. Delete Old Files wipes everything on your server, including your world. Leave it switched off, unless you want a completely fresh start.
  6. Click Install.
  7. Once it's installed, start your server.
