# ShareClick vs Universal Control

> Like Apple Universal Control, but across Mac and Windows. Share one keyboard, mouse, clipboard and files between a Mac and a Windows PC. Free, open source, encrypted.

Apple's **Universal Control** lets one keyboard and mouse roam across a Mac and an
iPad — but only inside Apple's ecosystem. There is **no Universal Control for
Windows**. ShareClick gives you that same seamless feel between a **Mac and a
Windows PC** — free, open source, and encrypted.

| Feature                   | ShareClick                       | Universal Control        |
| ------------------------- | -------------------------------- | ------------------------ |
| Price                     | Free & open source               | Free (built into macOS)  |
| Works with Windows        | **Yes**                          | No (Apple devices only)  |
| Mac ↔ Windows             | **Yes**                          | No                       |
| Mac ↔ Mac / iPad          | Any two computers                | Yes                      |
| Clipboard (text + images) | Yes                              | Yes                      |
| File transfer             | Yes (any pair)                   | Drag & drop (Apple only) |
| Setup                     | Shared passphrase + screen edges | Same Apple ID / iCloud   |
| Open source               | **Yes (MIT/Apache)**             | No                       |
| Encryption                | X25519 + ChaCha20-Poly1305       | Apple end-to-end         |

## Which should you pick?

* **Choose ShareClick** if one of your machines is a **Windows PC** — Universal
  Control simply doesn't support Windows. It's the practical "Universal Control
  for Windows".
* **Choose Universal Control** if you only ever move between **Apple devices**
  (Mac and iPad) on the same Apple ID.

Universal Control is a lovely feature, but it stops at the edge of Apple's
ecosystem. ShareClick delivers the same "push your cursor to the next screen"
experience across **Mac↔Windows**, with clipboard sync, file transfer, encryption
on every channel, and a UDP input path (\~6 µs transport overhead) for the lowest
possible lag.
