ShareCursor 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. ShareCursor 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	ShareCursor	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 ShareCursor 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. ShareCursor 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.
