CastleGuard
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
CastleGuard
Powerful Join Suite with Customizable Whitelisting
CastleGuard started off as a simple whitelist plugin. After using it and hearing feedback from other admins, we've decided that we could have done it better. Now Castle Guard can have customizable whitelist options set in your config as well as custom on-join commands.
As we're releasing a major 2.0 release so quickly we understand your configs will break. We've included the default config for the 2.0 release below for those that were early adopters.

join-commands:
enabled: false
commands:
- command: whisper %player% Hello World!
as_player: true
prefix:
enabled: false
prefix: "BR_"
whitelist:
enabled: false

verbose: false
modes:
- name: whitelist
message: "You are not whitelisted on this server."

- name: staff
