Claude Anywhere: My Tailscale + Termux Setup for 24/7 AI Collaboration

Boris Cherny’s Claude Code workflow went viral recently — 5 parallel Claude sessions, slash commands, subagents. Impressive stuff.

But here’s what most setups miss: what happens when you leave your desk?

I run 3-6 Claude sessions simultaneously too. The difference is I can pick up any session from my phone, anywhere, anytime. Here’s exactly how.

The Architecture

┌─────────────────┐     Tailscale VPN      ┌──────────────────┐
│  Android Phone  │ ◄──────────────────────► │   Workstation    │
│    (Termux)     │     Encrypted Mesh      │  (Claude Code)   │
└─────────────────┘                         └──────────────────┘

Components:

• Tailscale — Zero-config mesh VPN. Your devices get stable IPs on a private network.
• Termux — Full Linux terminal on Android. Runs SSH, tmux, everything.
• tmux — Terminal multiplexer on the workstation. Sessions persist when you disconnect.

Step 1: Install Tailscale on Your Workstation

# Arch Linux
sudo pacman -S tailscale
sudo systemctl enable --now tailscaled
tailscale up

# Ubuntu/Debian
curl -fsSL https://tailscale.com/install.sh | sh
sudo tailscale up

After authentication, your machine gets a Tailscale IP (like 100.x.x.x) and a MagicDNS name (like workstation.tailnet-name.ts.net).

Step 2: Set Up Termux on Android

Install Termux from F-Droid (not Play Store — that version is outdated).

# Update packages
pkg update && pkg upgrade

# Install essentials
pkg install openssh tmux

# Install Tailscale
pkg install tailscale
tailscaled &
tailscale up

Step 3: Configure SSH

On your workstation, ensure SSH is running:

sudo systemctl enable --now sshd

On Termux, create an SSH config for quick access:

mkdir -p ~/.ssh
cat >> ~/.ssh/config << 'EOF'
Host workstation
    HostName workstation.tailnet-name.ts.net
    User your-username
    IdentityFile ~/.ssh/id_ed25519
EOF

Generate a key if you don’t have one:

ssh-keygen -t ed25519
ssh-copy-id workstation

Now you can connect with just:

ssh workstation

Step 4: tmux for Persistent Sessions

The key to continuity is tmux. Your Claude sessions live in tmux on the workstation, so they persist even when you disconnect.

On your workstation, start Claude in a tmux session:

tmux new -s claude1
claude

Create multiple sessions:

tmux new -s claude2
tmux new -s claude3

From your phone, attach to any session:

ssh workstation -t "tmux attach -t claude1"

Or list all sessions and pick one:

ssh workstation -t "tmux ls"

My Daily Workflow

Morning at desk:

• Start 3-4 Claude sessions in tmux windows
• Each focused on different tasks (feature work, refactoring, tests, docs)

Throughout the day (mobile):

• SSH in from phone during commute, lunch, waiting rooms
• Check on long-running tasks
• Quick code reviews
• Brainstorm architecture decisions

Evening:

• Pick up where I left off on desktop
• Sessions maintained full context from earlier

Pro Tips

1. Termux Widget for One-Tap Access

Install Termux:Widget and create a shortcut script:

mkdir -p ~/.shortcuts
cat > ~/.shortcuts/claude1 << 'EOF'
#!/bin/bash
ssh workstation -t "tmux attach -t claude1"
EOF
chmod +x ~/.shortcuts/claude1

Now you have a home screen widget that drops you directly into Claude.

2. Mosh for Flaky Connections

If you’re on spotty mobile data, use Mosh instead of SSH:

# Workstation
sudo pacman -S mosh  # or apt install mosh

# Termux
pkg install mosh

# Connect
mosh workstation -- tmux attach -t claude1

Mosh handles connection drops gracefully — you won’t lose your session.

3. tmux Status Bar

Add this to ~/.tmux.conf to see which session you’re in:

set -g status-right '#S | %H:%M'

4. Quick Session Switcher

Create a script to list and attach to Claude sessions:

#!/bin/bash
# ~/.local/bin/claude-attach
SESSION=$(tmux ls -F "#{session_name}" | grep claude | fzf)
[ -n "$SESSION" ] && tmux attach -t "$SESSION"

Why This Matters

The bottleneck in AI-assisted development isn’t the AI — it’s availability. Ideas don’t wait for business hours.

With this setup:

• Continuity — Same context whether you’re on desktop or mobile
• Availability — Ship from anywhere
• Parallel work — Multiple Claude sessions, multiple contexts

The developers who’ll win in 2025+ aren’t optimizing for the most powerful desk setup. They’re optimizing for always-on availability.
