Capsem: Rust hypervisor from DeepMind team runs concurrent OCI containers for isolated AI agents
rakyll · x · 2026-10-28
Capsem, an open-source project praised by DeepMind folks, is out: a hypervisor written in Rust that runs concurrent OCI containers inside specialized hardened Linux VMs, aimed at shipping with AI securely.
Key facts:
- Targets Claude Code, Codex, and Cursor as isolated execution environments for coding agents
- Available for macOS (Apple Silicon) and Linux (x8664/ARM64) via .pkg/.deb or a one-line curl | sh install
- Ships an AI setup prompt so agents like Claude Code can self-install and configure environments
- TUI/GUI lets you run multiple agent sessions in parallel, each in its own VM
- Docs and install guides at capsem.org
