Set the prices for all "raw" Minecraft items and this tool will calculate prices for everything else, based on the crafting recipe. Download or fork from: https://github.com/botskonet/craftpricing See a demo at: http://69.168.54.10/craftpricing/ It's written in pure javascript so it can be easily run in your browser. You can also write additions to the export tool so you can get the pricing data into whatever format you need. Please report bugs, feature suggestions to me via the github issue tracker. Feel free to submit your data export functions so we can share those too.
