Quick Start - Installation

curl -fsSL https://raw.githubusercontent.com/Ark0N/claudeman/master/install.sh | bash

This installs Node.js, tmux, and Claude CLI if missing, clones Claudeman to ~/.claudeman/app, builds it. After install:

claudeman web
# Open http://localhost:3000 — press Ctrl+Enter to start your first session

Update to latest version:

curl -fsSL https://raw.githubusercontent.com/Ark0N/claudeman/master/install.sh | bash -s update

Run as a background service

Linux (systemd):

mkdir -p ~/.config/systemd/user && printf '[Unit]\nDescription=Claudeman Web Server\nAfter=network.target\n\n[Service]\nType=simple\nExecStart=%s %s/dist/index.js web\nRestart=always\nRestartSec=10\n\n[Install]\nWantedBy=default.target\n' "$(which node)" "$HOME/.claudeman/app" > ~/.config/systemd/user/claudeman-web.service && systemctl --user daemon-reload && systemctl --user enable --now claudeman-web && loginctl enable-linger $USER

macOS (launchd):

mkdir -p ~/Library/LaunchAgents && printf '<?xml version="1.0" encoding="UTF-8"?>\n<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">\n<plist version="1.0"><dict><key>Label</key><string>com.claudeman.web</string><key>ProgramArguments</key><array><string>%s</string><string>%s/dist/index.js</string><string>web</string></array><key>RunAtLoad</key><true/><key>KeepAlive</key><true/><key>StandardOutPath</key><string>/tmp/claudeman.log</string><key>StandardErrorPath</key><string>/tmp/claudeman.log</string></dict></plist>\n' "$(which node)" "$HOME/.claudeman/app" > ~/Library/LaunchAgents/com.claudeman.web.plist && launchctl load ~/Library/LaunchAgents/com.claudeman.web.plist

Windows (WSL)

wsl bash -c "curl -fsSL https://raw.githubusercontent.com/Ark0N/claudeman/master/install.sh | bash"

Claudeman requires tmux, so Windows users need WSL. If you don't have WSL yet: run wsl --install in an admin PowerShell, reboot, open Ubuntu, then install Claude CLI inside WSL: curl -fsSL https://claude.ai/install.sh | bash. After installing, http://localhost:3000 is accessible from your Windows browser.

Mobile-Optimized Web UI

The most responsive Claude Code experience on any phone. Full xterm.js terminal with local echo, swipe navigation, and a touch-optimized interface designed for real remote work.

	Terminal Apps	Claudeman Mobile
	200-300ms input lag over remote	Local echo — instant feedback
	Tiny text, no context	Full xterm.js terminal
	No session management	Swipe between sessions
	No notifications	Push alerts for approvals and idle
	Manual reconnect	tmux persistence
	No agent visibility	Background agents in real-time
	Copy-paste slash commands	One-tap /init

• Swipe navigation — left/right on the terminal to switch sessions (80px threshold, 300ms)
• Keyboard accessory bar — /init, /clear, /compact quick-action buttons above the virtual keyboard. Destructive commands (/clear, /compact) require a double-press to confirm — first tap arms the button, second tap executes — so you never fire one by accident on a bumpy commute
• Smart keyboard handling — toolbar and terminal shift up when keyboard opens (uses visualViewport API with 100px threshold for iOS address bar drift)
• Safe area support — respects iPhone notch and home indicator via env(safe-area-inset-*)
• 44px touch targets — all buttons meet iOS Human Interface Guidelines minimum sizes
• Bottom sheet case picker — slide-up modal replaces the desktop dropdown
• Native momentum scrolling — -webkit-overflow-scrolling: touch for buttery scroll

claudeman web --https
# Open on your phone: https://<your-ip>:3000

localhost works over plain HTTP. Use --https when accessing from another device, or use Tailscale (recommended) — it provides a private network so you can access http://<tailscale-ip>:3000 from your phone without TLS certificates.

Live Agent Visualization

Watch Claude's background agents work in real-time. Claudeman monitors every Task tool invocation and displays each agent in a draggable floating window with animated Matrix-style connection lines back to the parent session.

• Floating terminal windows — draggable, resizable panels for each agent with a live activity log showing every tool call, file read, and progress update as it happens
• Connection lines — animated green lines linking parent sessions to their child agents, updating in real-time as agents spawn and complete
• Status & model badges — green (active), yellow (idle), blue (completed) indicators with Haiku/Sonnet/Opus model color coding
• Auto-behavior — windows auto-open on spawn, auto-minimize on completion, tab badge shows "AGENT" or "AGENTS (n)" count
• Nested agents — supports 3-level hierarchies (lead session -> teammate agents -> sub-subagents)

---

Zero-Lag Input Overlay

When accessing Claude Code remotely (VPN, Tailscale, SSH tunnel), every keystroke normally takes 200-300ms to round-trip. Claudeman implements a Mosh-inspired local echo system that makes typing feel instant regardless of latency.

A pixel-perfect DOM overlay inside xterm.js renders keystrokes at 0ms. Background forwarding silently sends every character to the PTY in 50ms debounced batches, so Tab completion, Ctrl+R history search, and all shell features work normally. When the server echo arrives 200-300ms later, the overlay seamlessly disappears and the real terminal text takes over — the transition is invisible.

• Ink-proof architecture — lives as a <span> at z-index 7 inside .xterm-screen, completely immune to Ink's constant screen redraws (two previous attempts using terminal.write() failed because Ink corrupts injected buffer content)
• Font-matched rendering — reads fontFamily, fontSize, fontWeight, and letterSpacing from xterm.js computed styles so overlay text is visually indistinguishable from real terminal output
• Full editing — backspace, retype, paste (multi-char), cursor tracking, multi-line wrap when input exceeds terminal width
• Persistent across reconnects — unsent input survives page reloads via localStorage
• Enabled by default — works on both desktop and mobile, during idle and busy sessions

Extracted as a standalone library: xterm-zerolag-input — see Published Packages.

Respawn Controller

The core of autonomous work. When Claude goes idle, the Respawn Controller detects it, sends a continue prompt, cycles /clear -> /init for fresh context, and resumes — running 24+ hours completely unattended.

WATCHING → IDLE DETECTED → SEND UPDATE → /clear → /init → CONTINUE → WATCHING

• Multi-layer idle detection — completion messages, AI-powered idle check, output silence, token stability
• Circuit breaker — prevents respawn thrashing when Claude is stuck (CLOSED -> HALF_OPEN -> OPEN states, tracks consecutive no-progress and repeated errors)
• Health scoring — 0-100 health score with component scores for cycle success, circuit breaker state, iteration progress, and stuck recovery
• Built-in presets — solo-work (3s idle, 60min), subagent-workflow (45s, 240min), team-lead (90s, 480min), ralph-todo (8s, 480min), overnight-autonomous (10s, 480min)

Multi-Session Dashboard

Run 20 parallel sessions with full visibility — real-time xterm.js terminals at 60fps, per-session token and cost tracking, tab-based navigation, and one-click management.

Persistent Sessions

Every session runs inside tmux — sessions survive server restarts, network drops, and machine sleep. Auto-recovery on startup with dual redundancy. Ghost session discovery finds orphaned tmux sessions. Claude knows it's managed and won't kill its own session.

Smart Token Management

Threshold	Action	Result
110k tokens	Auto /compact	Context summarized, work continues
140k tokens	Auto /clear	Fresh start with /init

Notifications

Real-time desktop alerts when sessions need attention — permission_prompt and elicitation_dialog trigger critical red tab blinks, idle_prompt triggers yellow blinks. Click any notification to jump directly to the affected session. Hooks auto-configured per case directory.

Ralph / Todo Tracking

Auto-detects Ralph Loops, <promise> tags, TodoWrite progress (4/9 complete), and iteration counters ([5/50]) with real-time progress rings and elapsed time tracking.

Run Summary

Click the chart icon on any session tab to see a timeline of everything that happened — respawn cycles, token milestones, auto-compact triggers, idle/working transitions, hook events, errors, and more.

Zero-Flicker Terminal

Claude Code uses Ink (React for terminals) which redraws the entire screen on every state change. Claudeman implements a 6-layer anti-flicker pipeline for smooth 60fps output across all sessions:

PTY Output → 16ms Server Batch → DEC 2026 Wrap → SSE → Client rAF → xterm.js (60fps)

---

SSH Alternative (sc)

If you prefer SSH (Termius, Blink, etc.), the sc command is a thumb-friendly session chooser:

sc              # Interactive chooser
sc 2            # Quick attach to session 2
sc -l           # List sessions

Single-digit selection (1-9), color-coded status, token counts, auto-refresh. Detach with Ctrl+A D.

Ctrl+W	Close session
Ctrl+Tab	Next session
Ctrl+K	Kill all sessions
Ctrl+L	Clear terminal
Ctrl+Shift+R	Restore terminal size
