Sandboxes

What is Sandboxes?

Sandboxes lets you copy your survival world into a creative duplicate for experimenting with builds, redstone, or layouts, then return to survival when you are done. Your original world is never touched.

Features

One click creates a creative copy of any survival world. Switch back to your original world from the pause menu or a keybind.

You can keep several sandboxes per world, with create, sync, rename, and delete. Auto-sync re-copies your survival world into an existing sandbox to pick up new changes.

A red "SANDBOX MODE" label on the pause menu tells you where you are. Sandbox worlds are hidden from the main world selection screen.

There is a sandbox button in the pause menu, and an optional one in the inventory screen.

Requirements

• Minecraft 1.21.11
• Fabric Loader 0.15.0+
• Fabric API
• MenuKit (required)

Note

Sandboxes is designed for singleplayer worlds. It copies the world at the file system level, so it only works with local saves.
