Multi-Agent Orchestration

This section covers tools for running multiple Claude Code instances in parallel. For detailed documentation, see:

• AI Ecosystem - Gas Town, multiclaude, agent-chat, claude-squad
• Ultimate Guide Section 9 - Multi-instance workflows, git worktrees, orchestration frameworks
• Agent Tools: Beyond Claude Code - Hermes Agent, Codex CLI, Devin, CrewAI, LangGraph, and other tools that are not Claude-Code-specific

Quick reference:

agent-chat	Monitoring UI	Real-time SSE monitoring for Gas Town/multiclaude
Multica	Issue-driven control plane	Server-side coordination with local daemon execution across 26 agent CLI integrations
abtop	Fleet TUI monitor	htop-style: tokens, context %, rate limits, ports, subagent tree (3,393 stars, 2026-07-27)
Conductor	Desktop app	macOS parallel agents (also listed above)
Piebald	Desktop/web app	Multi-provider + Windows + hooks compat (also listed above)

abtop

A Rust TUI that shows all active Claude Code and Codex CLI sessions in one screen, like htop but for agent fleets.

Attribute	Details
Source	GitHub: graykode/abtop
Install	curl --proto '=https' --tlsv1.2 -LsSf https://github.com/graykode/abtop/releases/latest/download/abtop-installer.sh | sh or cargo install abtop
Language	Rust (ratatui)
License	MIT
Platform	macOS, Linux (WSL for Windows)

Key features:

• Auto-discovery of Claude Code and Codex CLI sessions from local process/file state: no API key, no auth
• Per-session bars: token usage, context window %, rate limit quota
• Orphan port detection with one-key kill (X)
• Subagent tree (Claude Code only)
• tmux integration: press Enter to jump directly to the session pane
• --once flag for snapshot output (CI-friendly)
• --setup to install a rate-limit collection hook
• 10 built-in themes including 4 colorblind-friendly variants (high-contrast, protanopia, deuteranopia, tritanopia)

Usage:

abtop                    # Launch TUI (requires 120x40 terminal, degrades gracefully to 80x24)
abtop --once             # Print snapshot and exit
abtop --setup            # Install rate limit collection hook
abtop --theme dracula    # Launch with a specific theme

Recommended setup with tmux:

tmux new -s work
# pane 0: abtop
# pane 1: claude (project A)
# pane 2: claude (project B)
# Press Enter in abtop to jump to the active agent's pane

Supported features by agent:

Feature	Claude Code	Codex CLI
Token tracking	✅	✅
Context window %	✅	✅
Rate limit	✅	✅
Subagents	✅	❌
Memory status	✅	❌

When to use: running 3+ concurrent agents across projects, hitting rate limits without knowing which session is responsible, or needing to spot orphaned ports left by a previous agent run.
