Beta
Free to use until October 31, 2026.
Slide your cursor off the edge of one screen and it lands on the next machine, keyboard and clipboard following it. This is the real thing, ahead of release — and we’d like to hear what breaks.
Version 2026.1.0-beta.2, released 29 August 2026 · macOS 14 or later · Windows beta coming
It expires. The beta runs through October 31, 2026, or until about two weeks after the release version ships, whichever comes first. It warns you daily during the final week, then stops and points you at the release version.
It never cuts you off mid‑session. Nothing interrupts you while your keyboard and mouse are on another machine — the beta waits until the cursor is back on its own computer before it says anything. When the beta has ended it simply declines to start sharing; your machines keep working normally on their own keyboards.
Install it on every machine you want to link. AcrossKM is peer‑to‑peer: each computer runs its own copy and they find each other on your network. A Mac and a Windows PC can share one keyboard — the Windows beta follows shortly, once its code signing is in place.
Nothing leaves your network. Keystrokes, mouse movement and clipboard travel directly between your own computers, encrypted, over your own LAN. The only connection to us is a daily check for a newer beta.
It updates itself. Newer betas arrive through the built‑in updater, installed only with your OK. The beta never installs the paid release on its own.
Tell us what you find. [email protected] — include which machines you were linking and what each was running.
