Keyleport

Remote keyboard/mouse input teleportation between machines over network.

Sponsor & Support

This project is fully developed and maintained thanks to the generous support of its sponsors and contributors.

What it does

• Captures keyboard and mouse on the sender and transmits events over network to a receiving device, then emulates input on the receiver.
• Uses UDP for high-rate mouse move/scroll; uses TCP for key presses.

High-level architecture

• src/flows

  • Contains possible work modes

• src/keyboard/

  • Logic for input handling and emulation

• src/networking

  • Part responsible for network connection, data transfer and running servers discovery

• src/utils/

  • Platform helpers

Build

• macOS/Linux: requires CMake; SDL3 detected via pkg-config. A helper script is included:

./scripts/compile.sh

• Windows: CMake project links user32 and ws2_32; build with your preferred generator (e.g., Visual Studio). A CI workflow for Windows exists.

Run

Start a receiver on the target machine:

./build/keyleport --mode receiver --port 8080

Start a sender on the source machine, pointing to the receiver IP:

./build/keyleport --mode sender --ip 192.168.x.y --port 8080

Transport selection (in sender):

• UDP for mouse Move/Scroll
• TCP for keyboard and mouse button Down/Up

Future Features

• Key mapping (eg: windows switches language like mac os)
• Local events emulation (in key-mapping mode only. so it's like using macros)
• Optimized binary data transferring
• Secured data transferring
• Possibly network events batching
