Unofficial Patch
Unofficial Patch is a Fabric server-side mod that fixes overlooked vanilla bugs and brings some game behavior into consistency.
What it does
Created by a community of contributors, Unofficial Patch targets bugs that the official game has left unaddressed. Its changes aim to make vanilla behavior more consistent across the game, and the mod is installed only on the server, so players connect without adding anything to their own installs.
The mod relies on Fabric API, which must be installed next to it. Files are published for Fabric alone, with builds covering 1.20.1 – 1.21.5, and the latest file, 1.0.0+1.21.1 for 1.21.1, was released on 2025-06-09 after the first release on 2025-06-03. The source code and issue tracker are public, but the license is All rights reserved, so the code is not open source.
Key features
Community bug fixes

Dyed shulker boxes in creative
In creative mode, shulker boxes can be colored with dye, which is otherwise not possible.
Time set to sunrise and sunset
The time of day can be set to sunrise or sunset, giving server owners a quick way to change the time of day.

How it compares
Carpet Fixes (unofficial port) is a Fabric mod for 1.21.11 that runs on client and server and is open source under the MIT License, so it has to be installed on both sides. Skeleton Aiming Fix is open source under the MIT License, with files for Fabric, Forge and NeoForge across 1.20.1 – 1.21.10 and a client and server environment. No Eating Animation is a client-side only Fabric mod for 1.21 – 26.1.2 under the MIT License, so it changes nothing on the server.
