For developers
HingeLab generators are part of this app. There is no public generator kit and no embed for other sites.
Each generator is a definition in the repository: defaults, a field list, presets, a build, and checks. The same shell draws the panels, the 3D view and the export. A third-party generator cannot be installed from outside that repository.
If that changes, this page will say how. Until then, use the generators that are already listed.
