Coop CLI Tool Creates Isolated VMs for AI Code Execution

Introduction to Coop

Coop is a newly released command-line interface (CLI) tool written in Rust. Its primary function is to create and manage isolated virtual machine (VM) environments. These VMs are specifically designed for executing code generated by AI models such as Claude Code and Codex.

Secure Code Execution

The core benefit of Coop is its ability to provide a secure sandbox for AI-generated code. Each VM offers full access to development tools like Docker, Git, compilers, and package managers, allowing for comprehensive testing and development. This isolation ensures that any potential issues or vulnerabilities in the AI-generated code do not affect the host machine.

Environment Characteristics

Coop's VMs are characterized by their isolation, reproducibility, and disposability. They are designed to be cheap to create and destroy, facilitating rapid iteration and testing cycles. This approach supports a workflow where developers can quickly spin up a clean environment, test code, and then discard the VM.

Installation and Usage

Installation involves either a curl command for the latest release or building from source using Rust's cargo. The setup process includes building a VM template image and, on Linux, installing Firecracker and fetching a guest kernel. macOS users need to install Lima separately. The tool is tested on macOS arm64 (Apple Silicon) and Linux x86_64, with arm64 builds available for Linux but untested.
