Dimensional Structure Restrict
Dimensional Structure Restrict limits which structures can generate in which dimensions, using whitelist and blacklist rules set in a JSON config file.
What it does
The mod lets a server owner or pack developer decide where structures may spawn, by setting rules per structure or per dimension. Rules are read from a config file that is created with example entries on first launch, and missing keys are regenerated automatically. Comments in the JSON are supported, so a config can be documented in place.
Each rule is either a whitelist or a blacklist entry that targets structure or dimension IDs. A flag can also be set so that a structure is placed only where it believes it was placed, which helps world designers keep generation predictable. Rule enforcement is written to the log with the structure and dimension involved, which simplifies debugging.
The mod is server-side only, so players join without installing it, and it is published for Forge and NeoForge with files for 1.20.1 and 1.21.1. The code is open source under the MIT License. Initial release targeted 1.20.1, and the 1.21.1 build followed later.

How it compares
Limited Structures is server-side only, under All rights reserved, and published for 1.20.1 – 1.21.1 on Forge and NeoForge. hxwi1structures runs on client and server and is released under the MIT License for the same versions. Dimensional Protection is also server-side only and MIT licensed, but its files cover 1.18.2 – 26.1.2 and it protects dimensions rather than limiting structure spawns.
