Crafting Codex

Crafting Codex is a free set of tools and calculators for Minecraft. Players pick Java or Bedrock and the version they play, and the answer is worked out from that release’s own game data.

The problem

Every version plays a little differently.

Minecraft has had well over a hundred releases across Java and Bedrock, and blocks, IDs and game rules change between them. An answer that is right for one version can be wrong for the next.

Crafting Codex reads each release’s own data, so the player gets the answer for the version they are actually on.

What it does

From the first block to the finished build.

01

Build generators

Roofs, circles, spheres and domes of any size, planned block by block and layer by layer.

02

Block data

Every block ID for the chosen version, Java or Bedrock, with its block states and a picture of each block.

03

Beacons

How many blocks a beacon pyramid takes, layer by layer, with the range and effects it gives.

04

Every version

A version picker for every Java release back to 1.0 and Bedrock back to 1.19.30, followed by every tool whose answer changes between them.

The catalogue

Built on the game’s own data.

The tools read the same data, release by release, so an answer in one tool agrees with the next.
