U-API

About U-API

U-API is a lightweight foundational library for Minecraft mods built around the U-API ecosystem.

It provides shared systems, utilities, and integration points used by dependent mods, helping them stay consistent, modular, and easier to maintain.

U-API is not meant to be a standalone content mod.
You should install it when another mod lists it as a required dependency.

What it is used for

• Shared API foundation for related mods
• Common utilities and internal systems
• Consistent integration between dependent mods
• Cleaner modular structure for future projects

For players

Install U-API only if a mod requires it.

By itself, U-API does not add new gameplay content, blocks, items, mobs, dungeons, or progression systems.

For modpacks

U-API can be freely included in public and private modpacks.
No additional permission is required. When possible, please use the official Modrinth or CurseForge distribution rather than redistributing standalone copies.
