Zombie Builder
by sMilizr
Zombie Builder lets zombies place blocks, so players who build for zombies can watch their work rise over time.
What it does
Zombies with this mod place blocks they reach, and the structures they make can grow vertically, horizontally or as bridges. Placed blocks disappear after a set period. Zombie Builder was made with a Zombie Apocalypse modpack in mind, and part of its path-building logic gives zombies the ability to break blocks, which is why the page recommends running it alongside mods that enable block breaking by monsters. It runs on the client and on the server, so both sides need the mod. Files are published for Forge on 1.20.1, and the license is All rights reserved, which means the mod is not open source.
Key features
Zombie block placement
Zombies place blocks in the spaces they reach, which lets them build as they move.
Three building styles
Placed blocks can extend up, out to the side, or across gaps as bridges.
Timed block removal
Placed blocks disappear after a period, so the structures do not stay permanently.
Path-building behavior
Some path-building logic allows monsters to break blocks, which the author pairs with compatible mods.

How it compares
Nekomata Zombie Apocalypse is client-side only, licensed under the MIT License and not open source, with Forge files for 1.20.1. Zombie Break & Build runs on the server only, is open source under the GNU Lesser General Public License v3.0 only, and covers Fabric, Forge and NeoForge 1.20.1 – 26.3, so it fits a different setup.

What the author says
Vertical building,Horizonal building and Bridge building. ## Recommendation: This mod is designed for certain Zombie Apocalypse Modpack. And some of its path-building logic is based on the ability of monsters to break blocks. Therefore, I recommend using it together with mods that allow monsters to break blocks.
