Unlocked World Border
by Ekical
Unlocked World Border removes the limit of the vanilla world border, so players can leave the border and still place, break and interact with blocks outside it.
What it does
Once a player goes past the border, the usual restriction no longer applies, and interaction with blocks beyond the edge works as it does inside. Crossing the border gives the player a purple-ish tint on screen, a visual cue that the limit has been passed. The mod can also shrink the border over time and scale the damage a player takes while outside it, so staying out for long becomes costly.
The mod is a Fabric build for 1.21.4 – 1.21.11, released under the Apache License 2.0, and its source code is public. It runs on the client and on the server, so both the server and every player need it for the feature to work across a multiplayer world. Only the Fabric loader is supported, and no other dependency is listed.

Who it’s for: The mod suits players who want to explore or build beyond the vanilla world border, and server owners who run border-based events or minigames where the edge should be crossable.
