Pearity
Pearity lets a modpack declare recipes that convert one item into another, so items that differ only by mod ID can be swapped in crafting.
What it does
Modded worlds often grow duplicates of the same item: a boat, a plank or a tool added by two mods under different IDs. Pearity handles this with data-driven recipes that turn one item into another without a fixed crafting grid. A rule can be shapeless, meaning the ingredients may sit anywhere in the grid, and can be written in both directions so that neither item is treated as the original.
Single rules can also use wildcards. A pattern such as minecraft:*_boat paired with a matching path in another namespace links every vanilla boat variant to its counterpart in one line, and the captured part of each ID carries over. Pearity runs on client and server, so the server and every player need it. It is published for NeoForge only, with version 1.0.0 for 1.21.1 as the single release, under the MIT License. The mod is not open source.
Key features
Shapeless conversion recipes
A recipe converts one item into another with the ingredients placed anywhere in the crafting grid.
Bidirectional rules
A rule can run both ways, so neither item in an equivalent pair is treated as the primary one.
Wildcard ID matching
Wildcards match parts of item IDs across namespaces and capture the variable part, so one rule covers many items.
Direct item mapping
A simple rule maps a single item, such as one vanilla boat, to its equivalent in another mod.
Compatibility
Latest build for each game version and loader.

Use cases
Interchangeable mod items
A pack that mixes vanilla content with a mod that duplicates it can let the two versions stand in for each other in recipes.
Progression-safe swaps
Rules can be limited to equivalent items, so pack authors avoid recipes that skip progression steps.
Who it’s for: Pack developers and server owners who run modpacks with overlapping items and want them to be interchangeable in crafting.
How it compares
Create TFC Unofficial Port is a NeoForge mod for 1.21.1 under the ISC License, and it is not open source. TFC Ore Tooltips is client-side only, is published for NeoForge 1.21.1 under the MIT License and is not open source. Pearity instead changes recipes on the client and server, so both sides need it.

What the author says
Modded worlds grow duplicates the way stone grows moss. Boats, planks, tools—same idea, different mods, different IDs. Functionally identical, mechanically divided. This mod exists to dissolve that friction. It lets you define shapeless item transformation recipes that convert one item into another based purely on…
