Everything Is BOM: Bill of Materials Encyclopedia

BOMwiki is a free, crowdsourced encyclopedia that breaks down over 4,800 products into their complete bills of materials, mapping nearly 30.4 million individual parts across 51 product domains. The platform uses an AI verification engine to check structural integrity of part hierarchies and allows community editors to contribute corrections, with changes reviewed before publication and verification status tracked for each product. Notable entries include a commercial airliner with 605,000 mapped parts and a jumbo jet with 5.6 million components.
