Get things from one computer to another — simple and fast.

fnull is a small, focused file-transfer CLI and library written in Go. It lets you send and receive files and directories through a relay server using short links. Designed for quick ad-hoc transfers and easy automation.

• Small, single-binary CLI (no heavy deps)
• Short human-friendly transfer codes / links
• Relay server + client model (future: P2P / E2EE)
• Cross-platform: Linux, macOS, Windows

On the sending machine:

fnull send path/to/file-or-folder
# -> prints a short link (or code) for the receiver

On the receiving machine:

fnull receive <fnull-link-or-code>
# -> downloads file(s) to current directory

Binaries are produced for Linux, macOS, and Windows. Detailed packaging instructions (Homebrew, apt, scoop, winget, .deb/.rpm, etc.) and signed releases will be published on the project website:
