Isolated VM environment for running Claude Code and Codex
What coop is
coop is a Rust CLI that manages disposable virtual machines where Claude Code, Codex, and Grok Build have full tool access: Docker, git, compilers, package managers, all without risk to your host machine. Each VM is isolated, reproducible, and cheap to create and destroy.

Transcript
Handing a coding agent the keys is a gamble. Coop is a Rust CLI managing disposable, reproducible virtual machines for Claude Code and Codex. Run coop up, then coop claude: every VM gets full tool access — Docker, git, compilers, package managers — while your host machine stays safe. The catch: only macOS arm64 and Linux x86_64 are tested; experiment, delete, repeat.
