SlimColonies 
Colonists do their work, you do yours
SlimColonies is a fork of MineColonies where colonists take care of themselves. Build your colony, assign workers, and everyone gets back to what they're doing.
Philosophy
MineColonies and SlimColonies serve different purposes. MineColonies offers deep colony simulation when that's what you're looking for. SlimColonies is for when you want to work alongside your colonists without managing them.
This matters most in complex modpacks. When you're already deep in GregTech or juggling multiple demanding mods, SlimColonies lets everyone focus on their own work. It feels more vanilla and fits naturally alongside other content.
Why SlimColonies?
Set it and forget it: Efficient behaviors are default. No research to unlock basic functionality, no separate progression systems to manage.
Modpack friendly: Works alongside complex mods without competing for your attention. No happiness tracking, disease management, or raid events.
Automation first: Visitor recruitment is free, couriers work efficiently from day one, and workers don't need hand-holding.
Development Status
Active development with tens of thousands of lines already removed.
