Linux VMs for developers and open-source tools for terminal access.
Shells — Full KVM virtual machines with Ubuntu 24.04, 200+ tools pre-installed, public IPv6, and dev preview URLs. Run Claude Code, Aider, or any AI coding agent in a persistent session. Connect from any terminal, browser, or phone.
latch — Terminal multiplexer with built-in SSH server and web access. Like tmux, but you can SSH into it or open it in a browser. One binary, zero config. Use it standalone on any machine — with a public IP, Tailscale, or WireGuard, no relay needed.
relay — SSH jump service for machines behind NAT. Register a device, connect from anywhere: ssh -J relay.unixshells.com default@mydevice.alice.unixshells.com. End-to-end encrypted — the relay never sees plaintext.
cterm — Terminal emulator built in Rust. Native UI on macOS, Linux, and Windows. Tab templates, themes, find-in-scrollback. MIT licensed.
mobile app — SSH, Mosh, and SFTP client for iOS and Android. Auto-discovers devices via relay and shells.
dev browser — Android browser with built-in Chrome DevTools for mobile web development.
