GroupManager vs ObjectDock

GroupManager is a free permissions plug-in for Bukkit and Spigot Minecraft servers. It lets server administrators organize permissions into groups, assign players and set up inheritance hierarchies with promotion or demotion paths. Permission rules can use wildcard, negative and exception nodes. Users and groups can be managed through configuration files, console commands or in-game commands, and permissions can be given expiration periods. Group and user variables include prefixes, suffixes and build status; PlaceholderAPI placeholders expose group details and permission checks to other plug-ins. The listed storage options include YAML, H2, MySQL, SQLite, PostgreSQL and MariaDB. Installation involves putting the JAR in the server's plugins folder and editing config.yml. The v3.2 release is listed for Minecraft 1.8 to 1.20+. GroupManager does not provide antigrief functionality; other plug-ins must handle that behavior. The project is released under the GNU General Public License version 3.
