Multipass

Multipass is a free, self-hosted permissions plugin built for Nukkit servers. It fits administrators who need structured user and group rules across multiple worlds or servers. The strongest case for it is its combination of inheritance, explicit denials, migration commands, and configurable storage; database deployments, however, add a DbLib dependency.

Overview

Multipass supplies a universal permission system for Nukkit, covering both individual users and reusable groups. Administrators can grant positive permissions, remove them, or apply negative permissions that explicitly block access. That distinction matters on busy servers where a broad group grant must be overridden for a particular user or role.

Groups can inherit from parent groups, allowing a shared baseline to be maintained once and extended for more specialized roles. Permissions and groups can also be tied to specific worlds, so a player’s access can change between game modes or other worlds. The configurable world-mirroring option is useful when world policies should track one another rather than be maintained independently.

Command access is controlled by the documented multipass.admin permission, giving operators a way to delegate administration without exposing every server privilege.

Key features

• Granular permission editing: Positive and negative permissions can be set or removed for users and groups. Explicit negatives are valuable for exceptions, but they also require administrators to keep precedence rules understandable.
• Inheritance: Parent groups provide common rules to child groups, reducing duplication as a server’s role structure grows. Small servers may not need this hierarchy, while larger communities benefit from centralized changes.
• World-aware policies: World-specific groups and permissions support different access models per world. World mirroring can reduce repetitive setup where several worlds should behave alike.
• Import and export: All groups and users can be exported to one file, and permissions can be imported from a file. This gives administrators a practical route for backups, migrations, or staging changes outside the live configuration.
• Storage choices: YAML, MySQL, and SQLite are documented backends. YAML is the straightforward choice for a single server; MySQL is more appropriate when a multi-server installation needs shared data, while SQLite offers a local database alternative. The documented database mode requires the separate DbLib plugin.
• Multi-server updating: A configurable auto-update interval can refresh groups and permissions across a multi-server system. It is useful for shared administration, though update timing should be chosen carefully when changes need to appear immediately.
• Plugin API: An API lets other plugins integrate with Multipass, making it more suitable as infrastructure for a broader Nukkit setup than as an isolated command tool.
• Translations and builds: The project is mostly translated into Russian, Turkish, French, and Korean, with community contributions invited through Crowdin. The README points to a latest development build and says the project page is outdated, so operators should use the maintained build path rather than assume the old page is current.

Pricing

Multipass has one free plan: Multipass — free. It is the complete permissions plugin rather than a restricted introductory tier, with no paid upgrade or trial term stated. That makes it suitable for any Nukkit operator who can host and maintain the software themselves. The trade-off is operational responsibility: storage configuration, updates, and any required companion plugin remain the administrator’s job.

Platforms

Multipass is self-hosted software for Nukkit. Its network support and multi-server update interval make it relevant to connected Nukkit deployments, while MySQL storage is aimed at installations that need shared database-backed data. It is not presented as a hosted web service or a general-purpose permissions product for other server platforms.

Who it's for

Choose Multipass if you run Nukkit and need world-specific access, inherited roles, explicit deny rules, or file-based migration between servers. It is particularly well suited to administrators managing several connected servers who want a shared backend and periodic permission updates. A small, single-world server with only a few roles may find its hierarchy and storage choices unnecessary. Teams unwilling to install DbLib should stay with YAML or SQLite rather than selecting database mode.

Pros and cons

Pros

• Detailed positive and negative rules handle exceptions cleanly.
• Group inheritance and world scoping support complex Nukkit role structures.
• Import/export commands simplify migration and preservation of permissions.
• YAML, MySQL, and SQLite cover simple local and shared-server deployments.
• API and multi-server updating allow integration into a wider server network.

Cons

• Database mode requires DbLib, adding another plugin to install and maintain.
• The README directs users to a development build because the project page is outdated.
• Self-hosting leaves upgrades, storage reliability, and configuration discipline to the operator.

Alternatives

GroupManager is another free, self-hosted option when you want GPL-3.0 licensed software without a paid plan. LuckPerms is the better alternative when you need a broader platform footprint spanning API, Linux, self-hosted, and web environments; it is free under the MIT license. MyPermissions suits readers seeking a free, open-source Minecraft permissions plugin with self-hosted and web platforms. BungeePerms is the targeted choice for BungeeCord/Velocity and Spigot/PaperSpigot networks rather than Nukkit. MultiPerms, PermissionManager, and ServerRoles are free alternatives when their respective permission-management approaches better match your server. Minecraft Permissions Plugins provides a broader category comparison.

Verdict

Multipass is a strong choice for Nukkit administrators who need inherited, world-aware permissions and a path to synchronize or migrate rules across servers. Its free complete plan, multiple storage backends, and plugin API give it useful depth without licensing cost. Look elsewhere if you need a hosted service, support for non-Nukkit platforms, or database operation without the added DbLib dependency.
