A quieter kind of precision

A good instrument disappears.
Then the work comes into focus.

Designed and assembled in small batches by six people who care about the things you only notice after a long day.

Built to be understood

Nothing
to hide.
Everything
in its place.

Five layers. Each one earns its place. Scroll through the stack, from the keys you touch to the weight that keeps everything grounded.

Thought through, down to the millimetre

Small details.
Long evenings.

Not a spec sheet for its own sake. A collection of decisions that add up to a keyboard that feels settled, from the first press to the last line.

01 FEEL

A little give.

A gasket mount and flex-cut plate take the edge off. The board has a measured softness, never a wobble.

02 SWITCH

Clear downstroke.

Factory-lubed long-pole linears. 45 grams to actuate, with 3.8 mm of travel and a tidy return.

03 CONNECT

Three places, ready.

Move from USB-C to 2.4 GHz or Bluetooth 5.3. Three remembered devices, one small switch.

04 MAKE YOURS

Open by design.

QMK and VIA compatible, with a browser configurator. Mac and Windows keycaps are in the box.

difference.

Every room hears a keyboard differently. Here are three little studies, generated in your browser. Put on headphones if you like.

A browser-made impression. Your room, caps and fingers will have their say.

A few good questions

Before it
lands.

Still wondering about a detail? Here are the ones that come up most.

When will my keyboard ship?

Pre-orders ship in 6–8 weeks. We assemble each small batch in Porto and will share a clearer dispatch window as your order gets closer.

Will it work with my computer?

Yes. Kestrel One works with macOS, Windows, Linux, iPadOS and Android over USB-C, 2.4 GHz or Bluetooth 5.3. Both Mac and Windows keycaps are included.

Can I change the switches or keycaps?

The hot-swap PCB accepts 3-pin and 5-pin MX-style switches. The standard MX stem takes the included keycaps and most aftermarket sets.

How long does the battery last?

Expect about 200 hours with lighting off, or about 40 hours with lighting on. Actual battery life varies with brightness and use.

What if it is not for me?

Take 30 days to decide. Returns are no-questions-asked, and every keyboard comes with a two-year warranty.
