Slimefun United
A modern, organised, community‑driven continuation of the Slimefun legacy — with full localisation support (WIP), active development, and compatibility with old saves.
✨ Magic, technology, automation, reactors, factories… all in one plugin.
🧪 What is Slimefun United?
Slimefun United brings together the best features from the original Slimefun and its most popular forks, combining them into a single, actively maintained project.
It offers a modded‑like experience on an unmodded Minecraft server, adding:
- ⚡ Energy networks
- 🔥 Reactors and generators
- 🏭 Automation systems
- 🧪 Magic altars and runes
- 📦 Item transport systems
- 🛠️ Hundreds of machines, tools, and gadgets
- 🌍 Full translation support
- 🔌 A huge ecosystem of addons
Compatible with worlds previously using:
- The original Slimefun 4
- Gugu Project’s fork
- Other community forks (on request)
Slimefun has existed since 2013, with 500+ items and hundreds of contributors. Slimefun United continues that legacy with modern standards, frequent updates, and a welcoming community.
