Open Parties and Claims
by thexaero
Open Parties and Claims lets players claim world chunks, forceload them and organize into parties, with server owners setting limits and permissions for each feature.
What it does
Chunk claims are owned by individual players by default. The owner can grant exceptions to party members and to groups they set up. Server owners can also switch on party-owned claims, and the mod offers a claim moderator mode that shows the player owners of party claims. Forceloading and claim anchors are controlled through the same permission system.
The mod exposes an API so other mods and plugins can read and change parties and chunk claims on both the server and the client. It integrates with Xaero's mapping mods, which should be updated to their latest versions. Required dependencies are Fabric API and Forge Config API Port. Fabric, Forge, NeoForge and Quilt builds cover 1.18.2 – 26.3, and server installation is required while client installation is optional. Its license is GNU Lesser General Public License v3.0 only, and it is open source.
Key features
Chunk claims and forceloads
Players claim chunks and forceload them, with limits set per player in the main config.
Parties and player groups
Players form parties and custom groups that can be used for protection exceptions in each claim.
Server claims
A permission lets non-OP players create server claims and turn on server claim mode.
Permission-based limits
Claim limits, group spacing and anchor range can be overridden per player with permission nodes.
Pluggable permission and party systems
Several common permission APIs are supported, along with Argonauts for parties, and the default system can be disabled in the config.

Use cases
Protecting a shared base
A group of players can claim an area and grant building access to its party members while others stay out.
Rank-based claim limits
Server owners can tie claim counts and forceloads to a player's rank through a supported permission system.
Who it’s for: Server owners who want to control chunk claims and party features, and mod developers who need an API for parties and claims.
How it compares
Use Server Name is a Fabric and Quilt mod for 1.20 – 1.21.9, published under the GNU General Public License v3.0 only and open source. Either side can run it, and a client without it is still fine. way2wayfabric is a client-side only Fabric mod for 1.19 – 1.20.4, under the MIT License and open source. Open Parties and Claims, by contrast, needs to be on the server and covers Fabric, Forge, NeoForge and Quilt.
