VillagersTradingPlus

The mod overrides vanilla villager trading through datapacks. A trade can be added, overwritten or removed for any profession, including the vanilla ones, and the currency of a trade can be changed from emeralds to another item. Each trade can set its maximum usages, villager experience, price behaviour and the amount exchanged. Trades can also be gated behind conditions tied to the surroundings and the world clock, and several datapacks can modify the same villager with their changes merged instead of the last one winning. Fourteen trade types are available, including plain item sales, weighted pools, structure maps and enchanted items.

The mod is a library for players who want to rewrite villager trading as a whole. Trade files are placed in a datapack under the mod's own namespace, and each profession file holds five tier arrays, with each trade written as a single object inside one of them. Vanilla trades are not stored in JSON, so replacing them means writing out every tier wanted. The trade types use the villagertradingplus namespace, and the older villagersplus namespace is still accepted by datapacks written before the split, though it logs a deprecation warning on load.

Files exist for 1.20.1, 1.21.1 and 1.21.8. Servers that run it need every player to install it too. It is released under the GNU General Public License v3.0 only, and the source code is published. The first file dates from 2026-08-07, and VillagersPlus is a reference mod built on top of it.
