Mod Fabric API

Fabric API, the foundation of Fabric mods

Fabric API is a modular library for Minecraft Java Edition that supplies the hooks, events, utilities, and shared interfaces used by many mods in the Fabric toolchain. It expands access to vanilla systems such as registries, particles, biomes, dimensions, networking, rendering, and resource handling, while improving compatibility between different projects.

Rather than adding a standalone gameplay theme, it provides the technical foundation that helps other mods run reliably on a Minecraft server or client. Its modular design keeps features focused, and BoxToPlay makes the server experience easier to manage when a modpack depends on this essential library.
