Openrig

OpenRig

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.

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:

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.
