I built CubeCursor because working across multiple computers shouldn't mean constantly switching between mice, keyboards, and finding ways to transfer files.

The idea is simple: make multiple computers feel like one big workstation.

With CubeCursor, you can move your cursor between computers just by reaching the edge of the screen. Your keyboard follows automatically, your clipboard is shared, and you can drag files, folders, and even browser tabs between machines.

A few things I particularly wanted to get right:

🔒 Privacy first: computers connect directly over your local network, with no cloud relay.
📁 Seamless file transfers: move files and folders between computers without extra steps.
🖥️ One setup, multiple machines: support for up to 9 computers.
💰 No subscription: a 14-day free trial, followed by a €9.99 lifetime licence.

CubeCursor currently supports Windows 10 and 11 (64-bit), and I'm working on the macOS version.

I'm launching this because I'd love to hear from people who actually use multiple computers every day.

I'd especially love your feedback on three things:

What's the most frustrating part of working across multiple computers today?
Which feature would make CubeCursor genuinely useful for your workflow?
What would you need to see to feel comfortable trusting an app like this?

Thanks for checking it out and helping me make CubeCursor better! 🙏
