Auction House
A server-side mod to add your items to an "auction house" where the item can then be sold to the highest bidder at any point in time.
About this Mod
This mod requires Fabric API.
This mod is in a highly experimental state. Do not use it on production servers.
Auction House is a server-side mod to add your items to an "auction house" where the item can then be sold to the highest bidder at any point in time.
Use the /sell command to add your items to the Auction House and /auctionhouse to access the Auction House.
This mod also has an "analytics" feature (controlled by the analyticsEnabled config option, enabled by default).
This feature basically sends data about the items in the Auction House to a website that converts it into neat graphs.
These graphs can be viewed by going to https://auction-house-api.onrender.com/view/<server_name>/ where server_name is the name set in the configuration file.
To see how your items' data is being used, go to https://github.com/Rafayel08/minecraft-auction-house-api (this is the repository that houses the source code for the analytics and graph generation)
Credits
- Huge shoutout to robotkoer for creating and maintaining the Fabulously Optimized modpack, as it was the only way I could play Minecraft properly! Without this modpack, I would have never played MC Java, and as a result, never gotten into modding the game.
- Another huge shoutout to Kaupenjoe for his Java Introduction and Minecraft Fabric Modding Tutorial playlists! They're a great resource for anyone who wants to get started with Minecraft modding.
- Thanks a lot to the Fabric community on Discord and GitHub Discussions and to Kaupenjoe's community on Discord for helping me out with the various issues I had when making this mod and tolerating my stupid mistakes.

Auction House server crashes on startup – what to do?
Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.20.4). You can switch loaders with one click in the panel.
Is Auction House compatible with fabric?
Auction House officially supports fabric for Minecraft 1.20.4. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Auction House – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Auction House consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
