GlitchCore is a Fabric, Forge, and NeoForge library mod for Minecraft Java from Glitchfiend. It adds no gameplay on its own: Biomes O' Plenty and Serene Seasons both require it to load, along with Tough As Nails, sharing loader-abstraction code and small utilities across those mods. Install it on client and server alongside whichever of them you're running.
What GlitchCore does
GlitchCore centralizes code Glitchfiend's mods share: loader-specific hooks, registry helpers, and small utilities that would otherwise be duplicated in each mod. It has no items, no blocks, and no config menu of its own. Its only job is making the mods built on top of it run, so installing it by itself changes nothing in a world.
Mods that require GlitchCore
- Biomes O' Plenty, a biome-expansion mod, required on Fabric, Forge, and NeoForge.

- Tough As Nails, Glitchfiend's survival-difficulty mod, also built on GlitchCore.
How to install GlitchCore
- 1.Install Fabric Loader, Forge, or NeoForge for your Minecraft version.
- 2.Download the GlitchCore jar from Modrinth, matching your loader and Minecraft version.
- 3.On Fabric, also download Fabric API; Modrinth lists it as a required dependency for GlitchCore's Fabric builds.

GlitchCore's Fabric, Forge, and NeoForge builds are all current through Minecraft 26.2, the latest year.drop release, so none of the three loaders is trailing the others right now. Older builds reach back to 1.10.2 for legacy Forge installs.
