Let Them Talk

A visual board for your agents. Each running Claude Code session is a card, and an arrow from one card to another tells both chats who they work with and why.

What it does

• Draw an arrow between two chats and it tells them who to talk to and why. They then talk through Claude Code's own messaging.
• Click an arrow to read what the two chats sent each other.
• Start a team: a master and up to 8 agents, each with its own role, prompt, model and effort.
• Terminal chats, Cursor chats and background agents share one board, with the subagents they run.
• Local and small: the server is one Python file that uses only Python's standard library, and nothing is installed into Claude Code.

Use cases

• You want your agents to communicate with each other.
• Your Claude CLI (or extension) sessions need to be aware of one another and exchange messages.
• You're working on a project where you need to stay on top of everything (not necessarily code-related).

Start

Needs Python 3.12+ and Claude Code (on Windows, both inside WSL).

• One line: uvx let-them-talk (needs uv; or pipx run let-them-talk). It starts the board and opens it in your browser; --no-open skips that. Its boards are kept in ~/.local/share/let-them-talk.
• From a copy of this repository, on Windows: double-click Start Let Them Talk.bat.
• From a copy of this repository, on macOS, Linux or WSL: ./start.sh, then open http://localhost:8765.

Click New board and pick a project folder: its running chats appear as cards. Drag the blue handle from one card onto another, then click Connect.
