LaunchGuard

LaunchGuard is a read-only pre-launch check plugin for Paper servers. It helps server owners check common configuration problems before players join, such as missing plugins, missing commands, missing worlds, unsafe configured locations, and basic permission node issues. This is not a gameplay plugin. It is a server administration utility.
