Tailored for you

When ordering your keyboard, you can choose from a broad range of options to get the everyday tool that suits you best

  • Choose your own mechanical switches
  • Easy customization of the layout with a GUI (Vial)
  • Optional per-key RGB
  • Optional tents to angle the keyboard to a more natural position

Custom hardware and firmware

I have carefully designed each keyboard case and PCB to get you the best experience possible.

They went through multiple revisions from customer feedback, and when ordering you will get the latest version – which you can also find on Github.

The QMK and Vial firmware was carefully crafted with the help of experts, to provide you a great out-of-the-box experience – and a good starting point if you want to make your own.

We <3 DIYers

While you can get prebuilts – I encourage you to try and build your own !

All of the cases and the PCBs required for a handwire are open-sourced on Github.

  • Kits available (with or without cases – if you have a 3d printer)
  • Detailed online build guide
  • Active Discord community for help and sharing
  • Everything open-sourced on Github
