Fabric Zones

Adds a "gamemode" that allows players to fly and have access to unlimited blocks (just like creative), but it prevents anything from leaving designated builder zones. The purpose is to prevent players from using creative hotbars to cheat in illegal items, or just using the access to the creative inventory to spawn in large amounts of items like diamonds or netherite.

Using Fabric Zones

It is still in prealpha stage, so I do not recommend using it, but you can download semistable builds the releases tab on GitHub
