YUNG's Better Caves
With YUNG's Better Caves installed on a server, underground terrain gets lava caverns, underground lakes and rivers, and flooded caverns that change the deeper a player digs.
What it does
The mod rebuilds the cave systems of the overworld. Caves stay small and plain near the surface, while lower layers produce larger and stranger spaces, including lava caverns, underground lakes and rivers, and flooded caverns. Generation can be tuned per dimension, and the configuration covers dozens of options that the author documents on the project wiki.
Installation needs Cloth Config API, Fabric API and YUNG's API, and Mod Menu is optional. It runs on the server alone, so players need nothing extra to join. Files are published for Fabric, Forge and NeoForge, with builds covering 1.20.1 – 26.1.2 and the open source code released under the GNU Lesser General Public License v3.0 only. The author lists a known conflict with one world-generation optimization mod on 1.20.1.
Key features
Deep cave layers
Caves grow larger and more varied the further below the surface a player digs, with different content at each depth.
Underground water and lava
Underground lakes, rivers, lava caverns and lava oceans appear as generated features in the terrain.
Flooded caverns
Caverns can be filled with water, creating underwater passages inside the stone.
Per-dimension settings
Cave generation can be configured separately for each dimension, through the mod's configuration options.

Use cases
Exploration worlds
Players who want deeper, more varied underground spaces to explore can use the mod on a server to change how caves look across a world.
Who it’s for: Server owners who want to change underground generation for every player, and players on a server that runs the mod who want to explore its new cave layers.
How it compares
Underground Rivers is open source under the MIT License, server-side only, and published for 1.20.1 – 26.2, so it covers a narrower set of underground water. Jean Caves is released under All rights reserved and is needed on the server, with the client optional, with files for 1.21.5 – 26.1.2 on Fabric, Forge, NeoForge and Quilt.
