Requirements

	Minimum
Server software	Paper, Purpur or Folia
Minecraft version	1.21+
Java	21+

BusyTab uses the Paper API, so it doesn't run on plain Spigot or CraftBukkit.

Optional plugins

None of these are required. BusyTab starts without them and hooks each one it finds.

Plugin	What it adds
PlaceholderAPI	Every placeholder BusyTab doesn't resolve itself, including %player_name%, %server_online% and %player_ping% from the default config. See PlaceholderAPI.
Vault or VaultUnlocked	%vault_rank%, %vault_prefix%, %vault_suffix%, and the rank used for sorting. See Vault & LuckPerms.
LuckPerms	%luckperms_prefix%, %luckperms_suffix%, %luckperms_primary_group_name%, and the sorting rank when Vault has none.
EssentialsX	AFK status for %busytab_afk%. See EssentialsX.
Nexo	<glyph:...> tags rendered as custom icons. See Nexo.

⚠️ The default config needs PlaceholderAPI

The config BusyTab ships with uses %player_name%, %server_online%, %server_max_players% and %player_ping%. Those come from PlaceholderAPI's Player and Server expansions. Without PlaceholderAPI they show up as raw text. Either install PlaceholderAPI and run /papi ecloud download Player and /papi ecloud download Server, or remove those placeholders from config.yml.
