About BOMwiki

BOMwiki is a free, openly editable encyclopedia of bills of materials: what products are made of, exploded down to individual parts. It currently maps 30,454,201 parts across 193,225 items. It is the flagship of The BOMwiki Project, which publishes an AGPL-3.0 public wiki-engine source set. The deployed service also includes separately licensed components.

Anyone can open an account and edit; here is how. Every page is versioned, and every change is attributed and reversible. New contributors' edits are reviewed before going live; trusted contributors publish directly. Disagreements go to each page's Discussion tab.

The catalog began as machine-generated content and is being verified page by page. Every page shows its verification status. Read how verification works, the analysis engine behind it, how the site is governed, and the contribution policies.

Every proposed change is screened by bomwiki-intelligence, an analysis engine that checks structure and function coverage before a reviewer sees the change. Machine actions such as catalog checks and cleanup passes run under the steward-bot account, with the same public history and revertability as any contributor.
