Claude Code Command Center (cccc)

A web-based monitoring and interaction hub for Claude Code sessions. Get real-time visibility into active Claude processes, browse session history, track usage costs, and chat with running sessions — all from a single dashboard.

Features

• Live Process Monitor — See all running Claude Code processes with PID, model, working directory, CPU, and memory usage. Auto-refreshes every 5 seconds via HTMX.
• Session Browser — Browse session conversations across all projects, including subagent threads, with messages color-coded by role (user, assistant, subagent, tool call).
• Plans & Tasks — View active plans and task lists associated with each session.
• Usage & Cost Tracking — Dashboard stats pulled from Claude's stats-cache.json.
• Session History — Recent global history from ~/.claude/history.jsonl.
• Chat Interaction — Send messages to running sessions directly from the web UI (uses claude --print --resume).
• PID-to-Session Resolution — Navigate to a session by PID with automatic resolution via open files, env vars, CWD matching, and most-recent fallback.

Quick Start

Requires uv and Python 3.12+.

# Clone and install
git clone <repo-url> && cd claude-code-command-center
uv sync

# Run
uv run cccc

The dashboard is served at http://localhost:18799.

Alternative run methods

uv run python -m src.main                                          # Direct module execution
uv run uvicorn src.main:app --host 0.0.0.0 --port 18799 --reload  # With auto-reload

How It Works

The app reads directly from Claude Code's local filesystem (~/.claude/) — no API keys or external services needed.
