# ShareClick vs Input Leap

> A free, open-source Input Leap alternative: encrypted by default, clipboard images, file transfer and mDNS discovery for Mac and Windows.

Input Leap is the community-maintained fork of Barrier — a solid, cross-platform
open-source KVM. ShareClick covers the same core idea for **Mac↔Windows**, but is
**encrypted by default**, ships **file transfer** and clipboard images, and uses
zero-config discovery so you never type an IP.

| Feature             | ShareClick                            | Input Leap            |
| ------------------- | ------------------------------------- | --------------------- |
| Price               | Free & open source                    | Free & open source    |
| Actively maintained | Yes                                   | Yes                   |
| Encryption          | **On by default (X25519 + ChaCha20)** | Optional (manual TLS) |
| Clipboard images    | Yes                                   | Text mainly           |
| File transfer       | **Yes**                               | Limited / No          |
| Auto discovery      | **mDNS (no IPs)**                     | Manual IP setup       |
| Input transport     | **UDP, \~6 µs**                       | TCP                   |
| Linux               | Work in progress                      | Yes                   |
| Mac & Windows       | Yes                                   | Yes                   |

## Which should you pick?

* **Choose ShareClick** for **Mac↔Windows** if you want encryption on by default,
  file transfer, clipboard images and mDNS discovery out of the box, with the
  lowest input lag.
* **Choose Input Leap** if you need broad **Linux** support and a very mature,
  multi-platform codebase.

Input Leap (and Barrier before it) proved how useful a software KVM is.
ShareClick is the newer, security-first take focused on Mac↔Windows: a UDP input
path (\~6 µs transport overhead), encryption on every channel, clipboard images,
file transfer, and mDNS discovery.
