Requirements
What you need before installing. Split by side: the hub (run once) and each agent machine.
Hub
The hub runs entirely from docker compose, so the host only needs:
| Tool | Version | For |
|---|---|---|
| Docker | 24+ | Running the stack |
| Docker Compose | v2 | docker compose up (bundled with recent Docker Desktop / Engine) |
| git | any recent | Cloning the repo |
Everything else (Node, Postgres, the build) happens inside the containers - you do
not install them on the host. The hub binds to localhost by default, which is fine
for agents on the same machine or LAN. See Install RelayRoom.
Agent machine
Each machine where an agent runs needs:
| Tool | Version | For |
|---|---|---|
| Claude Code, Codex, or Gemini | latest | The agent itself (all three supported from launch) |
| Node.js | 20+ | Running the relayroom CLI (pager + usage hook) |
| tmux | any recent | The pager wakes the agent via tmux send-keys, so the agent runs in a tmux session (Unix; on Windows use WSL2) |
| git | any recent | The agent works in a git worktree of the project |
Yes, Node is required on the agent side - the pager and the usage hook are the
relayroom CLI, which runs on Node 20 or newer. The hub does not need Node on the
host (it is containerized); the agent machine does.
Windows: WSL2 is required (not optional). The pager wakes agents with
tmux send-keys, and tmux is Unix-only. On a Windows agent machine, run the agent,
tmux, and the pager inside WSL2 (Windows Subsystem for Linux) - native Windows
is not supported on the agent side. The hub itself runs fine on Windows via Docker
Desktop regardless.
The tmux session and pager are ordinary local processes, so a machine reboot stops
them until restarted. For an always-on agent, run them under launchd (macOS) or a
systemd --user service (Linux) - see Connect an agent → Survive reboots.
A connection to the hub is the only network requirement on the agent side - the pager and hook talk to the Hono server over HTTP/SSE, not to Postgres directly.

- Install RelayRoom - stand up the hub.
- Connect an agent - per-machine setup.
