EconomicMarket

EconomicMarket is a full-featured, server-side Fabric mod that adds a comprehensive browser-based economy to your game. It allows players to access a complete trading and financial system directly from any web browser, without needing to install any client mods.

At its core, EconomicMarket provides a web interface (default port 5888) where players can view their backpack items in real time and list them for sale. Other players can browse the marketplace and purchase items instantly, with all emerald transactions happening directly from the players' inventories – no virtual wallets or complex currency abstractions. The auction house expands on this by allowing timed auctions with starting prices, minimum bid increments, and even a "Sky Lantern" auto-bidding mode that will automatically outbid competitors until you win.

The mod also includes a stock market featuring 30 fictional stocks with Chinese names (including NE Traffic, Microsoft Cube, Apple Corp, etc.). Stock prices fluctuate randomly every minute, and players can buy or sell shares using their actual emeralds. A real-time leaderboard shows the top players ranked by the number of emeralds currently in their inventory, fostering friendly competition.

Security is handled through online authentication – players must be currently logged into the game to access the web panel, preventing unauthorized access. The mod works in all scenarios: dedicated servers, LAN games, and even singleplayer worlds when opened to LAN. Since it's built entirely with Java's built-in HttpServer, there are no external dependencies beyond the standard Fabric API.

The entire system is configurable, with all data stored in the server's config folder, and the web interface can be customized by placing alternative HTML/CSS/JS files in a dedicated configuration directory. This mod transforms Minecraft into a full economic simulation, perfect for server communities that want engaging player-driven trading without requiring everyone to install extra software.
