How I Use Claude Code on My Phone with Termux and Tailscale (www.skeptrune.com)

You can run Claude Code from your phone by SSH-ing into a always-on desktop (or cheap VPS) and using Termux + Tailscale + tmux to get a persistent, secure mobile development environment. The author outlines a ~20-minute setup: install Claude Code (npm install -g @anthropics/claude-code) on your desktop, run Tailscale (curl install script; sudo tailscale up) to give devices a stable private IP (tailscale ip -4), install Termux from F-Droid and OpenSSH (pkg install openssh), then ssh your-username@<tailscale-ip> and use tmux (tmux new -s code / tmux attach -t code) to keep sessions alive. You can test sites on your phone by running dev servers with --host (Vite, Next.js examples) and open http://<tailscale-ip>:port. Practical tips include using ed25519 SSH keys (ssh-keygen; ssh-copy-id), SSH config aliases, tmux key remapping, and a small Bluetooth keyboard. Significance: this pattern gives power users full Unix control, direct port forwarding, persistent sessions, and access to local credentials and tooling without paying for managed mobile apps or cloud containers—the actual model compute still runs at Anthropic via Claude Code API calls, while your hardware handles orchestration and networking. The tradeoffs are mobile ergonomics (screen/keyboard) but the conversational Claude workflow maps well to mobile. Security-wise, Tailscale limits exposure by creating a private mesh, but standard SSH hardening and key management remain essential.
