# Factory OS

> Factory OS (styled Factory_OS) is an off-site construction company founded in 2017 in Vallejo, California that manufactures wood-frame multifamily and affordable housing modules on an assembly line and assembles them on site. It was recapitalized and renamed **Harbinger Homes** (Harbinger Production Inc.) in May 2024, and factoryos.com now 301-redirects every path to harbinger.homes. Factory OS publishes **no API, SDK, webhook surface, developer portal, or machine-readable specification**. This file is generated by API Evangelist from its public website; it is not published by Factory OS or Harbinger Homes.

## APIs

- No public API surface. On `harbinger.homes`, `/openapi.json`, `/openapi.yaml`, `/swagger.json`, `/v1/openapi.json`, `/api-docs`, `/docs`, `/redoc`, `/graphql`, `/llms.txt` and every `/.well-known/*` path return a real HTTP 404 (checked 2026-08-12).
- The legacy `factoryos.com` domain returns HTTP 301 to `https://harbinger.homes/` for every path, including `/api`, `/docs`, `/developers` and all `/.well-known/*` paths — a blanket domain redirect, not a served document.
- `api.factoryos.com`, `docs.factoryos.com`, `developer.factoryos.com`, `api.harbinger.homes`, `docs.harbinger.homes` and `developers.harbinger.homes` do not resolve in DNS.
- The company's GitHub organization, [github.com/factoryos](https://github.com/factoryos) (listed location Vallejo, CA; listed website www.factoryos.com), has no public repositories.

## What the company builds

- Industrialized off-site manufacturing of wood-frame housing modules for multifamily and affordable housing, produced by union carpenters across roughly two dozen assembly stations in a 33-step process inside a 275,000 sq ft facility in Building 680 on Mare Island, Vallejo, California.
- Published claims: about 50% less production time and 25% or more lower production cost versus conventional site-built construction; more than 4,000 homes delivered across California and Hawaii, roughly 90% of them affordable housing.
