# Open Keychain 3D

> Open Keychain 3D is a browser-based, open-source customizer for printable 3D keychains,
> nameplates, plant labels, and related small objects.

Geometry generation and STL/3MF export run locally in the browser. WebMCP is a progressive,
native-only enhancement: supported browsers may register tools while `/create` is open. The
optional API server is not required for the customizer workflow.
