The BOMwiki Project

How everything is made, free to everyone.

The mission

The goal of this project is to map every bill of materials in the world: what each product is made of, down to individual parts, in one shared graph anyone can read and improve.

We believe that is a net good, because manufacturing is a net good. Almost everything that keeps people alive and comfortable is manufactured, and the knowledge of how those things are put together is mostly locked inside companies. Opening it lowers the barrier to making, repairing, sourcing, competing, and learning. A student can see what is inside a wind turbine. A repair shop can find the part that actually fails. A founder can price a product before building it. An engineer in a country with no industrial base can study how the industrial world is assembled.

BOMwiki serves that mission the way Wikipedia serves general knowledge: openly editable, versioned, argued over in public, and honest about what has and has not been verified.
