Project Scraffold
by BAHE4KA1
Project Scraffold, a Fabric utility mod, lets a player replace a scaffolding block with a placeable block in one right-click.
What it does
Normally a player builds with scaffolding and later wants real blocks in those spots, which means breaking each scaffold first and then placing the new block. The mod collapses that into one action: right-clicking a scaffolding block with a placeable block in hand breaks the scaffold and places the selected block in its position. Either hand can carry the building material, and vanilla placement rules still apply, so a spot the held block cannot occupy keeps the vanilla behavior.
The change applies to singleplayer worlds and to multiplayer servers. Players need the mod for the swap, while a server can run without it; a client without the mod can still send the same action through normal interactions when the server runs it. The server keeps control of the final outcome, which can depend on latency, permissions and server rules. A scaffold broken this way drops nothing when there is room in the player's inventory, and otherwise the dropped scaffold appears at the replaced position.
Project Scraffold requires Fabric API and runs on Fabric for Minecraft 1.21.1 – 1.21.11, with files for each of the 11 release versions. The code is open source under the MIT License, and the source code and issue tracker are linked publicly. The latest file is 0.1.0 for 1.21.11, published 2026-05-13.
Key features
One-click block swap
Right-clicking scaffolding with a placeable block replaces the scaffold in a single action.
Main and offhand support
The held block can come from either hand, so the swap works with whichever hand carries the building material.
Vanilla placement rules
The normal placement checks stay in force, and a spot the held block cannot occupy falls back to vanilla behavior.
Inventory-aware drops
A replaced scaffold goes into the inventory when room exists, and otherwise drops at the replaced position.

Create Style Scaffolding is a Fabric mod for 26.1 – 26.3 that runs on client and server under the MIT License and is open source. Scaffolding Blueprint is open source under the GNU General Public License v3.0 only and covers Fabric and NeoForge for 1.21.1, with the same client and server environment. Easier Scaffolding goes further across loaders and versions, but it is not open source, is released as All rights reserved, and requires the server while the client stays optional.
