World Pre Generator
Servers that want chunks generated before players arrive can use World Pre Generator, a Forge and NeoForge mod that pre-generates Minecraft worlds with a command.
What it does
The mod pre-generates the dimensions of a Minecraft world ahead of play, so the chunks are already built when players explore them. Generation is started with a command, and the area is set by a center point and a radius counted in blocks or in chunks.
A semi parallel task count controls how much work runs at once, which lets the server owner balance generation speed against the load on the machine. Feedback messages report progress while a run is going. Only the server runs the generation, so the client is never asked to process it.
Installation is needed on the server only. Players join without installing anything, and the mod is built for Forge and NeoForge with files covering 1.17.1 – 26.3. Its license is All rights reserved, so the code is not open source.
Key features
Pre-generation by command
A command starts pre-generation of a dimension, so chunks are built before players reach them.
Center and radius settings
The area is defined by a center point and a radius, given either in blocks or in chunks.
Adjustable task count
A semi parallel task count sets how many generation tasks run at once, so the load can be tuned.
Progress feedback
Messages report on a run while it is going, so the server owner can follow the work.

Use cases
Friends playing on a private server
A group that plays together on its own server can generate the area they plan to explore before they join.
Renting a configured server
Players who rent a server that is already set up can ask the host to run a pre-generation without installing anything themselves.
Who it’s for: The mod suits server owners and hosts who want terrain ready before players arrive. Players who only join a server do not need to install anything.
How it compares
Chunky is the most common alternative for pre-generation. It works on Fabric, Forge and NeoForge across 1.13.2 – 26.3 and is licensed under the GNU General Public License v3.0 only, and can run on either side. Chunk Pregenerator covers Fabric, Forge, NeoForge and Quilt for 1.21.5 – 26.3 under a Creative Commons non-commercial license, and the server requires it while the client may skip it.

What the author says
This Mod can pre generate the Minecraft dimensions per command. The Mod is only needed on the server side, but can also be used on the client side. You need a server to play with friends? You don't know how to set up one? Just rent an already configured server!
