MaxFastBuild

by ifloppy

MaxFastBuild lets players place or break many blocks in one action, with the server deciding every shape and charge.

FabricGNU Lesser General Public License v3.0 onlyOpen source1.21 – 26.2

What it does

The mod is a Fabric client paired with a Paper plugin for Minecraft Java 26.2. The client shows a radial build menu opened by holding a key, and the chosen shape is sent to the server as anchors only. The server regenerates the full shape, validates it, and then applies the change, so the client never decides what gets placed or broken.

Tool-aware breaking respects the effective tool and keeps a durability floor, and optional Economy Vault and material inventory handling can charge for each block. Unfinished per-block or per-area charges receive partial refunds, and CoreProtect logging records actions under the player name when that plugin is present.

Installation needs Fabric on the client and Paper or Leaf 1.21.11 or newer on the server, with Java 21 or newer and Java 25 recommended for 26.2 stacks. Protocol responses use translation keys that the client resolves against its language files, and the mod is published for 26.2 with builds covering 1.21 – 26.2 across 13 release versions. It is open source under the GNU Lesser General Public License v3.0 only.

Key features

  1. Radial build menu

    Holding a key opens a radial menu, and releasing it selects the shape to place or break with the held item.

  2. Economy and materials

    Optional Economy Vault billing and a materials inventory, including shulker boxes, pay for placed blocks.

  3. Tool-aware breaking

    Breaking uses effective-tool checks and stops at a durability floor so tools are not worn out.
