Where to buy AT-AuctionHouse, what is included and what to do once you have the jar.
AT-AuctionHouse is a paid plugin. Buy it from either marketplace below and you get the same jar and the same support.
What you get
One jar, every version
Paper or Folia, 1.21.1 through the current 26.x line. Nothing to pick, nothing to match to your server build.
Menus you own
Every menu is built from gui.yml. Layout, materials, names, lore, stack size, glint
and custom model data.
Four languages
English, Spanish, French and Japanese ship with the jar. Add your own by dropping a
file into lang/.
Three storage backends
SQLite for a single server, MySQL or MongoDB for a network. Drivers download themselves at startup.
Cross-server mode
One shared auction house across a whole network, over Redis, with menus updating within about a second of a sale.
Real Folia support
Not just the folia-supported flag. Every piece of work is routed to the thread that
owns it.
After you buy
Download the latest build
Grab the jar from your purchase page on the marketplace you bought it from. You get every future update from the same place at no extra cost.
Install it
Follow Installation. It comes down to installing Vault and an economy plugin, dropping in the jar and restarting.
Tune the settings
Open config.yml and set your listing duration, price bounds and per-player slot
limit. See Configuration.
Restyle the menus
gui.yml decides what every button looks like and where it sits. See
Menus.
Pick a language
Set GENERAL.LANGUAGE and edit the wording to match your server's voice. See
Languages.
Questions before or after you buy go to the support Discord. See Support for what to include so you get an answer on the first reply.
Licensing
The jar validates its licence against the marketplace you bought it from. You never type a key in: the licence is embedded when you download.
A genuinely invalid licence disables the plugin. A network failure does not, so a marketplace outage or a firewalled server cannot take your auction house offline.
