ReplaceIT
by SrBatataZx
ReplaceIT lets players swap one block for another by right-clicking it while holding the replacement, without breaking the old block first.
What it does
When the mode is enabled, a player holding one block and right-clicking a block of a different kind replaces the target with the held block. The old block is swapped out directly, so a long run of walls, floors or pillars can be rebuilt without mining each piece and placing it again. The mode can be switched on and off, so ordinary Survival actions keep working when it is turned off.
The mod is built for large Survival builds where many blocks need replacing. It is lightweight and aims to avoid any noticeable performance cost while it is active. Its interface stays simple, with the mode toggle and the replacement action as the only controls players need to learn, although the configuration options go deeper for those who want them.
ReplaceIT is a Fabric mod for 26.2, published as version 1.0.0 and dated 2026-07-11. Client and server both need it, so a server that runs it requires every player to install it too. The code is open source under the MIT License, and the source code is publicly available.
