How to make hardware design fast

  1. Extensibility

    You'll never have unexpected problems assembling KittyCAD API calls into powerful hardware design features.

  2. Parallelization

    Every piece of infrastructure we build runs on the GPU, which means the software you build will be unbelievably fast.

  3. Modern file formats

    No approximations of geometry, no massive data transfers, just dense and accurate boundary representations.

KITTYCAD is made
for everyone
