Limited Structures
by Catomon
Limited Structures lets server owners cap how often each structure type generates in a world, so a given structure appears only once per dimension.
What it does
Structures can be set to generate only once, and each structure type can receive its own limit, with a default limit applied to all others. Because the mod stops a second structure of the same type from generating in the same dimension, each one stays unique across the world. Limits are set in a config file, and structures can be listed by id in a blacklist or switched to whitelist mode so that only the named ones are limited.
Server-side only, so players join without installing anything. Forge and NeoForge files exist for 1.20.1 and 1.21.1, with 1.0.2 as the latest build for each loader. The mod is released under All rights reserved and is not open source.

How it compares
Create: Easy Structures runs on Forge and NeoForge for 1.19.2 – 1.21.1, and both the client and the server need it. Structureful covers 1.20.1 – 1.21.1 on the same loaders, also as a client and server install. More Structure Control is open source under the MIT License and runs on Forge and NeoForge for 1.20.1 – 1.21.1, with both sides needed.

What the author says
With this mod every structure becomes unique since it prevents generation of more than one of each structure type per dimension. Both the default limit and per-structure limits can be configured.
