Modpack recipe conflict checker

When two mods put the same items in the same crafting grid for different results, the game keeps only one and the other item becomes uncraftable. Drop in your modpack and this tool lists every such clash between your mods and vanilla, and writes the KubeJS lines that remove the one you do not want.

What counts as a conflict

Two shaped recipes clash when they have the same size and every slot can hold the same item, including the mirrored pattern, since the crafting table accepts a recipe flipped left to right. Shapeless recipes clash when their ingredients can be paired up one for one. A slot that takes a tag, such as any planks, clashes with any recipe that takes one of the items in that tag. That is how a mod's crimson bookshelf ends up fighting the vanilla bookshelf.

Machines count too. Two smelting recipes for the same egg give you whichever the furnace finds first. The stonecutter is left out on purpose, because it lets you pick the result.

Recipes that only load when another mod is present are only checked if that mod is in your pack. Mods that have no wiki on this site yet are listed, and their recipes are not checked.
