Zuko

Private remote shells for machines you own—without inbound ports or a VPN.

zuko’s supported core is a Linux/macOS host and Rust CLI. Iroh handles dial-by-key reachability, relay fallback, NAT traversal, and encrypted transport; zuko handles a real PTY, one-time-code pairing, client authorization, and short reconnects.

Start here

• Install and connect on Linux or macOS.
• Run the Linux host under WSL2 on Windows, with the documented lifecycle limits.
• Download a client or build one from a fresh clone.

Use tmux, zellij, or screen for durable work. zuko deliberately does not store detached output or promise that PTYs survive a host restart.

Useful commands:

zuko ls
zuko rm <name>
zuko reset
zuko doctor
zuko upgrade --check
zuko app --doctor

The shared Flutter client is the sole graphical client implementation. Android, iOS/iPadOS, macOS, and Linux are Beta; the web client and Windows bundle remain Labs because their browser and installer/upgrade gates are incomplete. zuko app is also Labs. See Clients for current delivery channels and the roadmap for remaining promotion gates.
