Madnessverse
by LukaMadness
Madnessverse is a server-side API that lets other mods create, configure and remove dimensions at runtime on Minecraft 1.21.1.
What it does
The mod provides shared infrastructure for managing dimensions while the server is running. Individual mods decide which dimensions are created, configured or removed, and Madnessverse supplies the API they call to do so. It is intended as a library for mod developers who need dimensions created and removed on the fly.
Madnessverse requires Architectury API. Because the environment is server-side only, only the server needs to run it; vanilla clients connect without installing anything. Newly added or removed dimensions show up immediately in command suggestions on the server, but players on connected clients need to log out and reconnect before the changes become visible. The mod is released under the MIT License and is open source, with its source code and issue tracker public. Madnessverse is a server-side API for Fabric and NeoForge builds targeting 1.21.1, and it shares one codebase across both loaders through Architectury API.
