ThunderPerms
What it is
ThunderPerms is a free, Apache 2.0 permissions plugin for self-hosted Paper servers. It manages UUID-based player permissions, groups, memberships, true and false nodes, wildcards, temporary grants, and permissions limited to worlds. Groups can inherit from one another with cycle prevention and weights for priority, while expired temporary entries are cleaned automatically. YAML is the default storage backend, with optional SQLite, MySQL, and MariaDB support. Administrators can check and explain permissions, verify or repair data, view status, create backups, and inspect effective permissions. Audit logs record permission, group, repair, and backup actions. The plugin protects configured paths from directory traversal, redacts database credentials, and uses safer default TLS settings for MySQL and MariaDB. Its API supports checks, explanations, user and group inspection, assignments, known groups, and storage health. Integrations include AugmentedThunder plugins, StormEconomy, StormParty, and StormFactions. The listed compatibility details are Paper and Minecraft version 26.1.2.
