bomwiki.com is a free, openly editable encyclopedia of bills of materials: what products are made of, exploded down to individual parts. Every page is versioned, every change is attributed and reviewed, and every product links to the shared parts it is built from.

Sub-assemblies are shared: the same bearing or Li-ion cell is one node that appears on every product that uses it. The catalog is one graph.

• bomwiki: the public AGPL-3.0 wiki-engine source set used within bomwiki.com. Node.js and Postgres, no web framework, three runtime dependencies (pg, marked, sanitize-html). It is an allowlisted reading mirror for review and contributions, not a complete standalone checkout; private production integrations are omitted.
• PartMode: open-source, local-first 3D parametric CAD that runs in the browser, powered by OpenCascade WASM. Try it at partmode.com.
• BOM Intelligence: the analysis engine that reviews every proposed change. Closed source, but its interface is documented so any instance can supply its own analyzer.

• Fix the content: open an account on bomwiki.com and click Edit on any page. New contributors' changes are reviewed; trust is earned. See the policies.
• Improve the public engine: review the source and propose changes on BOMWiki/bomwiki. The mirror is not a complete standalone service, so read its scope and CONTRIBUTING guide first.
• Report security issues: privately, to admin@bomwiki.com. See SECURITY.
