Click Bordor Expander
by MaxStudios
Click Bordor Expander lets a player push the world border outward in one action, using items that add a chosen amount of space.
What it does
Right-clicking an expander item extends the world border by the amount the item carries, so the border grows at once instead of slowly over time. Each item has a different value, so the size of each step can be set to match the scale a player wants.
A challenge world, a server event or a progression run can all use the expanders, letting the play area widen as players reach set goals. Commands are also available, for example giving a player an expander that adds 1 block or one that adds 10000 blocks. The mod runs on Fabric for Minecraft 1.21.1 and is built for the client and the server together, so both sides need it.
Click Bordor Expander is released under All rights reserved and is not open source. The latest Fabric build is 2.1.0 for 1.21.1, published 2026-04-25, and the first release came out 2026-04-13.
