Custom-Build A Keyboard Fit To You
Don't Settle
For One-Size-Fits-All
Scan Your Hand, Build a Keyboard
Cosmos is the easiest way to design a keyboard around your one-of-a-kind hands. Scan your hand using just your phone camera, then fit a keyboard to the scan. The key positions align to your fingers' lengths and movement.
Add All The Things
Add a trackball, trackpad, encoder, or OLED display. There's support for MX, Choc, NIZ, and Alps switches, and almost every type of keycap. Plus with 15 different microcontrollers, you can mix and match all you like.

Print Worry-Free
Cosmos catches errors before you print and automatically fixes common model issues.

Cosmos lets you drag, drop, and rotate keys and trackballs into place.
Mix and Match Keycaps
Your artisans are now ergonomic. Whatever batch of keycaps you decide to use, Cosmos will arrange them to fit your desired curvature.

RGB and Hotswap Ready
Cosmos has first-class support for single-key PCBs, which let you easily integrate per-key RGB and hotswap sockets. It also has high-quality built-in-hotswap and PCB-less options if you're on a budget.

And last but not least…
Give it to your CAD friend
Every model can export to STLs, which are meant to be sent to your 3D printer or an online printing service, or to STEP models, which can be modified in CAD programs. If you don't like the way your model looks, ask your closest CAD guru to make adjustments.

Try the BetaPsst! Come here from my Dactyl generator? You should give Cosmos a try. It's changing a lot but it will give you a much better Dactyl-like case and microcontroller holder.
