UUID Generator
Make a fresh pack UUID and module UUID for your Bedrock addon’s manifest.json. Every pack needs its own — never copy them from another pack.
Your pair
Pack UUID header.uuid
Module UUID modules[0].uuid
Ready-made manifest
A starting manifest.json with your pair already filled in.
Linking a behavior pack and a resource pack? Make a second pair for the other pack, then list the other pack’s pack UUID under dependencies.
Just need some UUIDs?
These are random version 4 UUIDs made in your browser with its secure random generator. Nothing is sent anywhere.
