Dynamic Border
Dynamic Border lets a server owner set the size, growth and shrink behavior of the Minecraft world border, so the limit can change with the world and the players in it.
What it does
The mod replaces the static world border with a configurable one. A starting size can be set for each world, and the border can be told to grow, shrink or stay still. Its speed is expressed as blocks per player per minute, so a border can scale with how many people are online and widen or narrow as players join and leave a multiplayer server.
Dynamic Border is a server-side only mod, so players join without installing it. It is published for NeoForge 1.21.10 only, with the 1.21.10-1.0 file as the latest build, released 2025-11-18. The code is covered by All rights reserved and is not open source.
Key features
Custom starting size
The starting size of the border is defined in advance, so a world can begin small for a challenge map or large for open exploration.
Growth and shrink behavior
Each border can grow, shrink or hold its position, allowing the world to open up or close in as the server owner intends.
Blocks per player per minute
The expansion and contraction rate is set in blocks per player per minute, so the border responds to the number of people on the server.
Configurable tension
The border can close slowly over time, which adds pressure in survival play, or open gradually to support a story-paced exploration.

Multiplayer servers

Who it’s for: Server owners and map makers who want the world limit to be a game mechanic rather than a fixed boundary, including survival, SMP progression and controlled exploration setups.
