About the project
Rust CLI that runs Claude Code and Codex inside disposable isolated microVMs (Firecracker/KVM on Linux, Lima on macOS) with full tool access and no risk to the host machine.
Useful for
- Run Claude Code in an isolated VM so it can install packages and edit files without touching the host
- Spin up a separate VM per project with coop up and coop claude to run agents in parallel
- Recreate a clean VM after risky agent experiments instead of manually cleaning up the system

Star trust
Growth looks organic: forks and discussion are in line with active projects, and stars arrive unevenly, the way people give them.
These are heuristics, not a verdict: we judge by the repository’s behavior, not by a list of stargazers.
