ItemCore — Lightweight Core · Unlimited Expansion
Are you tired of those bulky, feature-bloated item library plugins?
You know the ones — they try to do everything, yet master nothing.
They cram your server with features you never use, and drag performance down with every tick.
Why not try this free and useful item plugin?
ItemCore was built to solve this once and for all.
We don't pile on features. We give you the purest, most stable, and fastest item core.
The base plugin contains only two things:
- Item Attribute System (NBT, metadata, custom tags)
- Item Creation API (clean commands and developer-friendly interfaces)
- Abnormal effect (Stack abnormal effects to apply special effects on enemies)
Every extra feature is delivered via official or community add-ons — on demand.
Want a forging system? Add ItemCoreForge
Want a trinkets/accessories system? Add ItemCoreTrinkets
Want more MythicMobs integration? Add ItemCoreMythic
More standalone expansion packs will be released in more places in the future.
Load only what you need — keep it lean.
- Unused features are never loaded — server resources go where they matter
- Each add-on updates independently without conflicts
- Core API stays stable; add-ons are hot-swappable (some may require a restart)
Who is it for?
| Server Owners | Want a clean, controllable item foundation, not a "all-in-one" monster |
|---|---|
| Players | Less lag, faster responses, and only features that actually matter |
