Foundations
by lluckymou
Foundations is a Fabric datapack that trims Minecraft's core mechanics back to a minimal progression, instead of adding hundreds of new items.
What it does
Foundations recalibrates existing mechanics rather than introducing new content. Its author describes a minimal set of changes intended to reshape most of the gameplay experience. Resources regain the survival weight they had in the Alpha and Beta eras, and the progression is kept deliberately short.
Several changes are visible in play. Right-clicking most blocks with a stick can occasionally start a temporary fire. Campfires are crafted unlit. Items dropped on death glow with an outline nearby, so they are easier to find. The lighting and food behaviour are also adjusted to match this simpler progression.
The mod is a Fabric datapack for Minecraft 1.21.9 – 1.21.11, with the latest file 1.1.0 for 1.21.11 released 2026-01-25. The server must run it, while a player may leave it out. The code is under the MIT License, and the source code, issue tracker and wiki are public.
Key features
Primitive lighting
Right-clicking most blocks with a stick can occasionally start a temporary fire, replacing some item-based lighting.
Unlit campfires
Campfires are crafted unlit, so players must light them before using them for warmth and cooking.
Glowing death drops
Items dropped on death emit a glowing outline nearby, making them easier to recover.
Minimal progression
Core mechanics are adjusted in place, and no hundreds of new items are added to the game.

Use cases
Vanilla-style survival

Who it’s for: Players and server owners who prefer a slower, more restrained survival progression over new items and content.
