SimpleCore by Cooshh
by cooshh
SimpleCore is a common base layer across the Simple mods, supplying economy support, coin handling and shared utility code that those mods draw on.
What it does
SimpleCore supplies common systems used across the Simple mod collection, including shared economy and coin support and general utility code. Its main role is as a dependency: it adds little visible gameplay content on its own, and the mods that use it supply the features players see. Fabric API is required alongside it.
The mod is installed on both the client and the server, and every mod that depends on it must run on the same setup. SimpleShop and SimpleOreGen are named as requiring SimpleCore to work correctly. Files exist for Fabric only, for game version 1.21.11, with 0.1.0 as the latest file from 2026-05-10. It was first published on 2026-05-03 and is released under the MIT License, which does not make it open source.
Integration helpers let other Simple mods hook into the shared systems without each one carrying its own copy. Because the core is common, players and server owners install it once and reuse it across the collection.
Key features
Shared economy and coins
Provides the coin and economy systems that other Simple mods draw on, so they do not each implement their own.
Common utility code
Bundles general helper code used across the collection, reducing duplicated logic between mods.
Integration helpers
Offers hooks that let dependent Simple mods connect to the shared systems in a consistent way.
Client and server support
Runs on both sides, so the systems stay in sync between players and the server they join.

Use cases
Running the Simple collection
Server owners who run SimpleShop or SimpleOreGen install SimpleCore on the server and on each client so the dependent mods work correctly.
Who it’s for: Server owners and players who use mods from the Simple collection on Fabric for 1.21.11 and need the shared economy and utility systems installed.
How it compares
Culiatum Economy is a Fabric economy mod for 1.21.11 that is open source under the CC0 1.0 Universal license and runs on client and server. Coin System is also Fabric for 1.21.11, under the MIT License, but it runs on the server side only, so players join without installing it. SimpleCore is a shared core library rather than a standalone economy, so it fits as a dependency where those mods do not.
