Cold Biomes Only
by mittensDev
Cold Biomes Only is a world-generation mod that limits a new world to cold biomes, for a hardcore winter challenge.
What it does
Players who want a survival challenge can create a world made only of cold biomes. The generated terrain draws from several frozen and snowy biomes, with Dripstone Caves also present underground. Other biomes do not appear in the world.
The server must run the mod, because the server decides the biome set; clients may leave it out. The mod is published for Fabric, Forge, NeoForge and Quilt, and also as a Data pack for server platforms. Files cover 1.21.9 and 1.21.10, and the latest build is 1.0-alpha2+mod for 1.21.10, released 2025-12-16 on the alpha channel. The code is licensed under the Apache License 2.0 and is open source, with public source code and an issue tracker.
Key features
Cold-only world generation
New worlds generate only the cold biomes listed in the mod, leaving warm and temperate terrain out of the map.
Frozen ocean and peaks
Frozen Ocean, Deep Frozen Ocean and Frozen Peaks appear as the main water and high-altitude terrain.
Snowy land biomes
Snowy Beach, Snowy Slopes, Snowy Taiga and Ice Spikes make up the land areas of the generated world.
Dripstone caves
Dripstone Caves are kept underground, so the cave systems follow the same cold theme.
Datapack option
The same biome set is also offered as a Data pack, for servers that want to load it without a mod loader.

Use cases
Survival challenge
A survival server can start a world in cold biomes only, so players must work with a single climate for the whole game.
Adventure maps
Map makers can use the cold-only setting as the base for an adventure map with a consistent winter look.
Who it’s for: Players looking for a survival challenge in winter terrain, and server owners who want a themed world type for their community.
How it compares
No More Snowy Biomes is a Forge-only mod for 1.20.1, meant for the server alone and not open source, so it covers a different version and loader set. Snowy Ruins is open source under the MIT License, works on Fabric, Forge, NeoForge and Quilt for 1.21 – 1.21.10, and needs the server while clients may skip it. Cold Biomes Only also needs the server while clients may skip it, is licensed under the Apache License 2.0, and targets 1.21.9 – 1.21.10 across the same four loaders.
