Better Nether

Better Nether is a adventure mod created by Quiqueck. Expands the Nether with new biomes, vegetation, materials, and structures, adding depth and variety to the hostile dimension. As a adventure mod it concentrates on exploration, structures, and new things to fight, and it has been downloaded around 20 million times, which puts it among the options players reach for in this space.

Better Nether is built for players who want the Nether expanded with new biomes and life. It adds fresh Nether biomes, plants, and mobs, deepening a dimension that even after vanilla updates can feel sparse. It is approachable enough to drop into a world and use right away, with little setup required.

The mod is available for Forge and Fabric, so it fits a range of modpacks and launchers. It currently targets Minecraft 1.20.1. 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.

Better Nether works particularly well alongside BCLib. It depends on BCLib, so those must be present and on the same loader and version. Because it ships for both Fabric and Forge-family loaders, it slots into most popular modpacks regardless of which side they are built on.

Better Nether has a modest footprint for what it adds and is widely used in modpacks without notable performance concerns.

If you are comparing options, similar mods include Incendium and Nether's Delight. They cover comparable ground, so the right choice usually comes down to your loader, version, and the rest of your pack.
