Your keyboard and mouse stay here.
one desk, one pointer
Your cursor
doesn’t know
where a screen ends.
OneMouse makes two computers feel like one continuous workspace over your private local link—Wi‑Fi, Ethernet, or a direct Thunderbolt Bridge. Slide off the edge, keep moving, keep typing.

01 — The handoff
No pairing ritual.
Just cross the edge.
Set up a host and connect a companion machine on the local IPv4 path that suits your desk: Wi‑Fi, Ethernet, or a direct Thunderbolt Bridge. When your pointer reaches the configured edge, OneMouse carries compact movement and input messages to the next screen.
OneMouse discovers non-internal IPv4 interfaces and sends its input protocol directly over UDP—no cloud relay and no proprietary Thunderbolt driver.
Companion
Receives the movement naturally.
02 — Built to disappear
The useful part is
what you don’t notice.
Pointer follows you
Cross the boundary you set and keep moving on the adjacent screen.
Typing goes with it
Basic keyboard input travels with your active cursor, without switching keyboards.
Scroll stays in flow
Keep reading, navigating, and working with the same scroll wheel.
macOS release

feel smaller.
