Piggy Admin

The mod is a server-side administration tool for managing anti-cheat settings and moderating a Fabric server for 1.21.1. A central configuration controls whether features such as fast placement and tool swapping are permitted, and each option can be turned on or off on its own. Each joining player receives the active configuration automatically, so the rules apply without a manual step on the player's side.

Enforcement is strict: the server disables the restricted cheats on the client, and client-side overrides are ignored, which keeps play fair on the server. An ore cache manager tracks the locations of valuable ores in the background using a concurrent map, so the tracking has little effect on the main server thread. The mod works alongside client-side companions such as Piggy Build and Piggy Inventory.

Piggy Admin runs on the server only, so players join without installing anything. Its commands require operator level 2 or higher. The mod is published for Fabric only, with the latest file 2.0.1 for 1.21.1, and the code is released under the CC0 1.0 Universal license, which places no restrictions on use. The author describes it as a personal project.
