Before you build

What to look for.

  1. 01

    What’s actually open

    Check the six parts on each card. A public repository is a start, not a complete build.

  2. 02

    The maker’s cost

    Costs are the maker’s documented figures with their scope. Check what the figure includes.

  3. 03

    Can you sell it?

    The repository license is not always the hardware license. Each listing explains the difference.

Costs are the maker’s documented figures, with their original scope. Stars are recorded GitHub snapshots, never a quality score. Search the whole collection
