DonutAH (Retired)

While a player browses the Auction House on DonutSMP, the client reads the first page of listings and sends the new or changed entries to a shared market database. Duplicate listings are filtered out before submission, and each price is stored per unit, so a stack of 64 cobblestone is recorded as one cobblestone price. Enough players running the mod build up the data without any manual step.

Hovering an item shows its average market price, with enchantment-specific pricing for enchanted gear and custom labels that a player can attach to an item. Shulker boxes display the total value of their contents, and shop prices are shown alongside market prices, including whether an item is overpriced or a good deal. A /donutah command and a web dashboard at donutah.efm.lol expose the same market data outside the game.

The mod runs on the client only, so servers need nothing installed and players need only this mod. It is published for Fabric and targets recent builds through 26.1.2. The code is not open source and is released under All rights reserved, though source code is available publicly. Data is submitted anonymously, and no personal information is collected.
