Overview
Biomes O' Plenty is a world-generation mod created by Glitchfiend. One of the most popular biome mods, adding over 50 new biomes with unique terrain, vegetation, and atmosphere to world generation. As a world gen mod it concentrates on terrain, biomes, and the shape of the world itself, and it has been downloaded around 130 million times, which puts it among the options players reach for in this space.
Biomes O' Plenty is built for players who want a large, classic library of new biomes to explore. It adds scores of biomes with their own trees, plants, and blocks, and remains one of the most modpack-friendly worldgen mods around. It is approachable enough to drop into a world and use right away, with little setup required.
The mod is available for Forge, Fabric, and NeoForge, so it fits a range of modpacks and launchers. It currently supports Minecraft 1.20.1, 1.20.4, and 1.21.1, spanning the 1.20.1 to 1.21.1 releases. It runs on both the client and the server, so on a multiplayer server every player who connects needs it installed alongside the server itself.

How to install Biomes O' Plenty
Biomes O' Plenty supports Forge, Fabric, and NeoForge; pick one loader (you cannot mix them) and install it for your chosen Minecraft version. It is built for Minecraft 1.20.1, 1.20.4, and 1.21.1, so make sure your profile uses one of those versions.
- 1Choose and install one mod loader from Forge, Fabric, and NeoForge for a Minecraft version this mod supports (1.20.1, 1.20.4, and 1.21.1).
- 2Check the download page for any required libraries. Biomes O' Plenty lists no hard dependencies here, but it is always worth confirming for your exact version.
- 3Drop the Biomes O' Plenty .jar file into your instance's mods folder. On a server, place it in the server's mods folder instead, and make sure every connecting player has it too.
- 4Launch the game with that loader profile and confirm Biomes O' Plenty appears in the in-game mods list; if it does not load, re-check the loader, the Minecraft version, and any library requirements.
Supported Minecraft versions: 1.20.1, 1.20.4, and 1.21.1. Always download the build that matches your version exactly, as mod files are version-specific.
