OPD · Open Product Description

How a product is made, written down.

Open Product is an open library of how real products and their factories are built. Each release is an OPD: the parts, the BOM, the assembly, the full line, and what goes wrong. Every value says where it came from.

What's in an OPD

OPD does for a physical product what OpenUSD does for a 3D scene. It's one structured description anyone can take to recreate the product, simulate it, fork it, stand up a line for it, or learn from it.

Think of it as open weights for hardware. Open weights give you the finished model without its training data. An OPD gives you the product and its factory, without the maker's private data.

02 · The record

Every value is a claim

Nothing in an OPD is stated without a source. Each value carries where it came from and how confident we are, so you can see what was measured and what was worked out. When we infer, we mark it, and we ask the people who know to correct us.

Each OPD is private, embargoed to a date, or public.

03 · The frame

Every factory has three versions

N−1We deliver

The product and its line, rebuilt from the box. Retail units, CT scans, teardowns and public filings.

NYours

The line you actually run. It belongs to you, and we never build it.

N+1We deliver

The line you'll run next, tested in simulation before it exists.

04 · First release

OPD-0001: the Joy-Con

Our first release is a product many people have held. We're building it from retail units and public sources only. Before any release goes public, the maker gets a private preview.

One email when it ships. Nothing else.
