  We present an open-source database of superconducting quantum device designs
that may be used as the starting point for customized devices. Each design can
be generated programmatically using the open-source Qiskit Metal package, and
simulated using finite-element electromagnetic solvers. We present a robust
workflow for achieving high accuracy on design simulations. Many designs in the
database are experimentally validated, showing excellent agreement between
simulated and measured parameters. Our database includes a front-end interface
that allows users to generate ``best-guess'' designs based on desired circuit
parameters. This project lowers the barrier to entry for research groups
seeking to make a new class of devices by providing them a well-characterized
starting point from which to refine their designs.
