Simple Market [UA]
by Pro777
Simple Market is a Forge economy mod for 1.20.1 that simulates buying and selling, with prices that move as players trade.
What it does
Items carry a buy price and a sell price, and the screen shows hints about their initial values. Each player has an account of their own, so trades are tracked per person. Demand for a product rises when players buy it and falls when they sell it, and the price follows that change. Demand also recovers on a timer, adjusting once a minute in each direction until it settles.
Which products appear, and at what prices, is set in JSON arrays for items to sell and items to buy, with a product listing that gives name, price and unit. A product can be given an NBT tag, so a container item can be listed with its contents. The config file controls these values, and the mod is available in English and Ukrainian.
Simple Market is open source under the GNU Lesser General Public License v3.0 only. It is published for Forge only, with files for 1.20.1, and the client and server both need it, so every player and the server must run it. The latest Forge file is 2.0 for 1.20.1, released on 2026-05-26.
Key features
Buy and sell prices
Each item shows a buy price and a sell price, with hints that explain the starting values for a trade.
Demand-driven prices
Selling lowers demand and price in proportion to the amount sold, while buying raises them relative to the amount bought.
Timed recovery
Demand and price move back toward their baseline every minute, so a market does not stay shifted after a burst of trades.
Configurable product lists
Sell and buy products are defined in JSON arrays, with name, price and unit for each listing.
NBT-tagged products
A listed product can carry NBT data, for example a container item with a set of contents, for purchase-only entries.
