Fab's Server Tweaks
by fabbe50
Fab's Server Tweaks is a server-side gameplay mod for Fabric and NeoForge, with quality-of-life changes to vanilla logic that players on a server can use without installing anything extra.
What it does
Server owners install the mod on the server, and it needs Architectury API and Cloth Config to run. Fabric API is needed on Fabric, and the configuration screen is reached through the mod's own config, where settings are stored and can be changed. Most gameplay tweaks are switched on and off with gamerules, and a vanilla-like mode can be enabled to apply a much broader set of tweaks.
Vanilla clients connect and play normally, so a player needs nothing installed to join a server that runs the mod. Installing the mod on the client is optional and only adds better piston visuals, since custom piston presentation logic is otherwise shown with vanilla client visuals. Recipe viewers such as JEI or REI are recommended on both sides to find recipes that the mod changes, and Polymer, Lootr and Universal Ores can be added for extra server-side content. The license is the GNU Lesser General Public License v3.0 only, and the source code and issue tracker are public. Builds cover 1.21.11 – 26.1.2, with files for 26.1.2 as the latest.
Key features
Modular server tweaks
The mod is split across several control layers, each covering a set of quality-of-life changes to vanilla logic.
Piston move override
Pistons can move blocks that have the normal DESTROY push reaction, so they move them instead of breaking them.
Enchantment and recipe changes
Add-on packs can extend enchantments and change crafting recipes on the server, without any client install.
Gamerule control
Most gameplay tweaks can be turned on or off with gamerules, so server owners pick which changes apply.
