ccshare

What is ccshare?

ccshare is a free, open-source tool (MIT licensed) that enables live multiplayer terminal sessions for CLI coding agents. You wrap any terminal command in a real PTY and get a 6-char code — anyone who joins sees the exact same terminal and can type simultaneously. Works over LAN, cloud tunnel, or Tailscale. Compatible with Claude Code, Codex, and any terminal-based agent.

Key features

• 6-char code sharing — anyone joins via CLI or browser, no install needed
• LAN discovery via UDP broadcast (transmits only a hash, never the raw code)
• Browser-based terminal access with zero installations
• macOS menu bar integration with session control, joiner count, and notifications
• Bundled cloudflared for free auto-generated quick tunnel (no account needed)
• Self-hosted relay and Tailscale direct support for private networks
• Session recording (--record saves to asciinema .cast files)
• Compatible with any terminal agent: Claude Code, Codex, opencode, kimi, etc.
• Read-only mode for presentations and live demos
• Zero accounts, zero telemetry, MIT licensed
• Bidirectional hosting and joining
• tmux-style 'smallest terminal wins' pty resizing

Who it's for

• Remote pair-programming with CLI coding agents (up to 5 people)
• Live coding demos and technical presentations
• Rubber-ducking sessions where multiple developers contribute
• Recording and sharing terminal agent sessions for documentation
• Collaborative debugging sessions with shared agent context

When not to use it

Not a general-purpose collaboration tool — it's specifically for terminal/CLI sessions. If you need document co-editing or visual IDE collaboration, look elsewhere. The cloud tunnel session dies when the host disconnects unless you self-host the relay.
