# ShareClick vs. alternatives

> How ShareClick compares to Synergy, ShareMouse, Barrier, Input Leap, Mouse Without Borders and Apple Universal Control.

ShareClick is a **free, open-source software KVM** focused on Mac↔Windows, with
the lowest input lag we can squeeze out, encryption on every channel, and
zero-config mDNS discovery. Here's how it stacks up against the alternatives.

## What we took from each

* **Lan Mouse** → UDP input path + active/inactive state model → lowest latency.
* **Deskflow/Synergy** → portable key IDs, clipboard & file transfer features.
* **ShareMouse** → the UX goal: drag-and-drop files should "just work".
