Version support
We maintain full game data for 32 Minecraft Java versions from 1.17 through to the latest, 26.3. Each version has its own validated item, block, entity, enchantment, effect, biome, and recipe data so IDs and names are always accurate to the version you're playing. The version selector lets you switch instantly.
Mod support
Browse item IDs, blocks, entities, and recipes for popular mods across multiple Minecraft versions. More mods coming soon.
Privacy and security
Your world and player files are never uploaded — all file editing happens locally on your device. The only thing sent from a player file is its UUID, used to show that player's name and skin.
