World Border Evolved
World Border Evolved gives server owners a set of tools for running border-based minigames, such as battle royale events with a shrinking playable area.
What it does
Phased border shrinking lets a server set the size, shrink speed and damage of each stage, so a match can tighten the playable area on a schedule. Total automation spreads players, clears their inventories, assigns starting kits and sets game modes and PVP rules, so a round starts without manual setup. Weighted randomizer settings let a server list several game configurations, run them in an automatic start loop and control how often each one comes up.
The mod is server-side and needs Fabric API. The server must run it to host the events, while players may add it on their client but do not have to install it. Files are published for Fabric only, for 1.21.1, with 1.1.2 as the latest build from 2025-09-29. The code is MIT licensed but the project is not open source.
Key features
Phased border shrinking
Each stage sets its own border size, shrink speed and the damage players take outside the border.
Juggernaut mode
One super-powered player must survive against all the others, with custom potion effects added through the config files.
Saved kits
A kit captures a player's full inventory, including armor and off-hand items, and can be given back to any player instantly.
JSON game configuration
Game modes are defined in a JSON file that server owners can edit to change variables and build their own events.

Use cases
Battle royale events
A server can run a timed battle royale in which the border closes in stages until one player remains.
Hunter and hunted rounds
Juggernaut mode pits one strong player against the rest of the server, suited to intense hunters-versus-hunted games.
Who it’s for: Server owners who run recurring minigames and community events. Players only need the client mod if the server asks for custom effects or features.
How it compares
Advancement Border is server-side only and open source under the MIT License, with files for 1.21 – 1.21.4. Unlocked World Border is client and server, open source under the Apache License 2.0, and covers 1.21.4 – 1.21.11. TheDru juggernaut is a Fabric mod for 1.21.11 – 26.2 under All rights reserved, so it is not open source and targets a later range than this mod.
