OpenRig at a glance
Checked 18 Oct 2026OpenRig lets you describe a group of coding agents in a YAML file and boot them with one command; each agent runs in tmux on your machine. It drives the Claude Code and/or Codex accounts you already have, so a paid plan is needed. It requires Node.js 22 or 24 and tmux on macOS or Linux; Windows only through WSL2. Apache-2.0 licence. It is a free tool and does not replace a paid product we list.
