Isolated VM environments for running Claude Code, Codex, and Grok Build.
Pronunciation: "coop" (/kuːp/) — one syllable, rhymes with "loop", like the thing you keep chickens in. Not "co-op".
coop is a Rust CLI that runs Claude Code, Codex, and Grok Build in disposable virtual machines with Docker, git, compilers, and package managers. The VM isolates guest execution from the host. Live mounts and file sync, direct credential forwarding, and host editors cross that boundary when enabled. The optional credential proxy keeps supported raw credentials on the host.
Check the platform prerequisites.
Install the latest release:
curl -fsSL https://raw.githubusercontent.com/trailofbits/coop/main/install.sh | bash
Build the VM template image:
coop setup
Keep coop updated:
coop update
See Getting Started for building from source and alternative installation methods: Homebrew and Nix.
Start an instance for the current project and launch an agent CLI:
cd ~/code/my-project
coop up
coop claude
# or
coop codex
# or
coop grok
