PluginQuery is a Spigot and BungeeCord plugin that allows plugins to send plugin messages without having to require the player to be online on the server. An alternative to Socket, Plugin Message, and Redis.​

Plugin Query allows you to send Plugin Message across bungeecord servers even if the server is empty (has no player online). This is a great alternative to regular plugin message, where it needs at least 1 player to be online on the server in order to send a plugin message. This is also better than using sockets, since you don't have to open another port for your server, it will use your main server port instead!.​
