Develop Engineering CAD Software with Powerful Design Features

KittyCAD is the Design API

Develop Engineering CAD Software with Powerful Design Features

Build modern design software with GPU-native speed and cloud streaming technology. KittyCAD is Zoo’s Design API, built from the ground up on our custom CAD Engine. Modern speed, globally accessible.

Our Design API

Validated through software built by our team, like Zoo Design Studio, and through tools created by our customers, we bring the industry's infrastructure up to speed so you can focus on what matters.

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
