cmux-ssh-here lets you share a LAN shell in one command without SSH setup

A developer has released cmux-ssh-here, an open-source tool that spins up a temporary, token-authenticated SSH server on a local machine with a single npx command. The tool generates a shareable link and QR code, allowing other devices on the same network to access a shell instantly without configuring sshd, keys, or firewall rules. Authentication relies on a bearer token embedded in the link, which rotates every three minutes, and the entire server — including the host key — is destroyed when the process is terminated. The tool supports plain SSH clients, deep links for apps like Termius and Blink, and optional tmux integration for persistent shared sessions. Designed strictly for trusted local networks, it runs on macOS and Linux with Node 18 or later and is available on GitHub under the MIT license.
