Paradigm Realms

Each player can hold one permanent realm on a server. A realm is protected by built-in rules that cover blocks, containers, entities, fluids, explosions, pistons and teleports. Owners can set it to public or private, manage members, visitors, invitations and bans, and transfer ownership. Realms can be reset, and public realms appear in a realm directory.

Players choose one of the starter presets the server allows, such as starter islands, flat plots, empty platforms or custom bases tuned to a modpack. Server administrators can import schematic structures, and imports are checked before players can use them. Wilds are shared, temporary areas for exploration and gathering, with resources, structures and mobs. Random teleportation checks world borders and terrain collisions first. Wilds can be regenerated while the server runs or offline, and an older generation stays on disk until its replacement passes verification. Administrators can regenerate Wilds without affecting player realms.

The mod is server-side only, so players join without installing it, though the requirement note says client installation is needed. Its dependency is Fabric API on Fabric. It is released under the Creative Commons Attribution Non Commercial No Derivatives 4.0 license and is not open source. Files are published for Fabric, Forge and NeoForge for 1.21.1, and the source code and issue tracker are public.
