CraftChain QA

Your game works—until a player reaches a crafting recipe that asks for an item that doesn't exist.

CraftChain QA is an offline spreadsheet checker for indie games with crafting systems. Point it at an item catalog and a recipe table. It highlights problems with clear references and suggested fixes, before those problems reach your players.

CraftChain QA Lite (free)

- Finds duplicate and missing item/recipe IDs

- Flags unknown ingredients, unknown outputs, malformed quantities, missing names

- Checks comma-separated CSV files locally in your browser

- Includes intentionally broken sample data to demonstrate checks

CraftChain QA Pro ($12)

- Includes everything from Lite

- Flags circular ingredient dependencies

- Reports crafting outputs not reachable from the base-item assumptions

- Estimates ingredients and intermediate crafting steps for a target quantity

- Exports findings to CSV or JSON for your task tracker

No setup: Download the ZIP, extract it, and open `index.html` in your browser. Everything runs on your own computer; your game data is never uploaded.

Works with: Any engine or workflow that can export item and recipe tables to CSV (including Godot and Unity). The app is not an engine plugin.

CSV format:

- Items: `id,name` with optional `type,value,source`

- Recipes: `id,output,output_qty,ingredients` with optional `station`

- Ingredients example: `wood:2;stone:1`

Important limits: CraftChain is a static checker, not an in-game playtester. Items with no recipe are assumed obtainable. It cannot inspect game-specific loot drops, quests, economy rules, or runtime state. Alternative recipes are flagged; Pro's material explorer follows the first recipe for each output. Its raw-material estimates can overcount unused surplus from shared intermediate batches. A clean report is not a guarantee of a bug-free game.
