Jake's Economy
by DevJake
Jake's Economy adds a player-driven market to a Fabric world, where item prices move with buying and selling and trade runs on a live coin currency.
What it does
Prices in the market rise and fall with supply and demand, following a logarithmic curve. Buying an item pushes its price up and selling pushes it down, and arrows beside each item show whether its price has recently moved. A price history graph keeps saved values for set intervals and can be viewed from the market screen. Prices and trends sync live to online players after each trade, and new players receive the full market configuration when they join.
Items can be gated behind advancements, so players must earn a required achievement before they can buy or sell certain goods, which suits progression servers. The mod works on a dedicated server as well as in single-player. It includes native integration with CobbleDollars, and when both are installed their currencies sync automatically. The code is open source under the GNU Lesser General Public License v2.1 or later, and files are published for Fabric 1.21.1 only, with 1.3.0+1.21.1 as the latest build from 2026-06-29.
Key features
Supply-driven prices
Buying an item drives its price up, selling drives it down, and the change follows a logarithmic curve.
Market browser and trading
The market GUI lists items by category, search and tabs, sorts them alphabetically, and includes an auction house.
Item detail trades
The item detail screen trades a single item or a bulk quantity up to 64 at a time, with custom amounts available.
Price history graph
Saved prices are plotted on a graph at set intervals, viewable from the market GUI beside trend arrows.
Achievement-gated items
Market items stay locked until the player earns the matching advancement, so progression controls access.

How it compares
CobbleDollars Ticket is a Fabric mod for 1.21.1 that is client and server and not open source, under the MIT License. CobbleDollars Notes is also for 1.21.1 and client and server, under the MIT License, and is open source. Donut's Auctions is open source under the MIT License, client-side only, and covers only 1.21.10 – 1.21.11, so it does not overlap with Jake's Economy's 1.21.1 build.
