openrig

Define a team of Claude Code, Codex and Pi agents in YAML and boot it with one command: persistent tmux-backed seats with roles, shared context and owned work, steered via a lead agent.

Curator's take

Use it when you already live in Claude Code/Codex and want a standing team — lead agent, specialists, stable addresses — rather than one-off sessions. Skip it if you want a hosted platform or Windows-native setup (tmux, macOS/Linux/WSL2 only), and read the permissions section first: the kernel operator runs with broad, prompt-free access by default.

OpenRig

npm version npm downloads License: Apache 2.0 GitHub stars

A harness wraps a model. A rig wraps your harnesses. Define your agent team in YAML, boot it with one command. Claude Code and Codex in the same rig, managed as one system.

OpenRig is open-source software for building and running your own network of agents. It turns AI coding agents from a pile of terminal sessions into a persistent, organized team. Talk to a lead agent about the outcome you want; it can coordinate specialists across teams and bring you results and decisions that need your attention. Start with a repository and one useful change, then keep the team's work and context at the same addresses.

It's the open-source system behind my AI civilization experiments.

See it running

The OpenRig TUI: the build rig as a graph, then as a table of seats with runtime, model, context and state, then one seat in detail (real recording, 10 seconds)

Start here: the guided first-use path: install, talk to the kernel operator, then choose a team for your first useful change.

Install and first run

Let your coding agent set it up. First check that node --version shows 22 or 24: the command below needs Node.js and the npx that comes with it. Then, in your project folder, add OpenRig's rigs skill to the agent you use:

# Claude Code
npx skills add https://github.com/mvschwarz/openrig/tree/v0.7.5/skills/rigs --skill rigs --agent claude-code
# Codex
npx skills add https://github.com/mvschwarz/openrig/tree/v0.7.5/skills/rigs --skill rigs --agent codex

Then type /rigs in Claude Code, or $rigs in Codex, and say what you want built. The skill has your agent tell you what it will run and change before it does, install OpenRig, open the OpenRig view and pass your goal to OpenRig's operator.

You need Node.js 22 or 24 (22 on Apple silicon), tmux, macOS or Linux (WSL2 on Windows), and Claude Code or Codex signed in. One provider is enough to start.

Already have OpenRig? Use the tag that matches rig --version, or upgrade first.

Prefer to type the commands yourself? Install it yourself ↓

Requires Node.js 22 or 24 and tmux, on macOS or Linux, and one working Claude Code or Codex account: one is enough, since the kernel operator adapts the shipped starter team to whichever you have. On Linux, the distribution's own Node.js can be older (Ubuntu 24.04's is 18); install a supported version with nvm (nvm install 22) or NodeSource. On a Mac with Apple silicon, use Node.js 22 (compatibility history). On a Mac where you aren't an administrator, or where Homebrew belongs to another account (its brew install is refused), install Node.js in your own home folder with nvm: run touch ~/.zshrc (a new Mac account has none, and nvm's installer only adds itself to a profile file that already exists), then nvm's install command, for nvm v0.40.8 curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.8/install.sh | bash (nvm's page
