Nexus4CC
Your Claude Code, Everywhere.
Showcase
Highlights
| AI on the go | Your time is fragmented. Your AI shouldn't be. Command Claude Code from your phone — commuting, in a meeting, or away from your desk. |
| Built for touch | Not a desktop terminal shoehorned onto mobile. Swipe between windows, pinch-to-zoom, configurable toolbar — purpose-built for fingers. |
| Full context, always | Claude Code runs on your machine, in your tmux sessions — your full codebase, your history, your preferences. Not a cloud chat that forgets everything. |
| Fire and forget | Give the instruction, close your phone. Your agents keep running. Open later — everything's exactly where you left it. |

- Clone this repo and
cdinto it - Run
node scripts/setup.js— handles deps, frontend build, PM2, and first tmux session - Verify:
pm2 statusshowsnexusonline → openhttp://localhost:59000
Prerequisites: Node.js 20+, tmux. PM2 is installed automatically if missing.
Default login password: nexus123 (user can change it in .env after setup).
Deployment
Expose securely without port forwarding via Cloudflare Tunnel or Tailscale.
Requirements
| Dependency | Version | Note |
|---|---|---|
| Node.js | 20+ | |
| tmux | any recent | |
| PM2 | any recent | auto-installed by setup.js |
| OS | Linux / WSL2 |
Security
Nexus is a single-user, self-hosted tool — not a multi-tenant platform.
- 🔒 bcrypt (12 rounds) password hash + JWT (30d)
- ⚠️ WebSocket token passed via query string — enable TLS in production
- 🛡️ Run behind firewall, VPN, or tunnel — do not expose directly to the internet
