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 safely included in modpacks when required by other mods from the same ecosystem.
