Open source update 🤯
CubeSandbox v0.6.0 is live with Kubernetes and Volume support, led by these two community requests:
🔹 Cube no longer needs a separate sandbox cluster. It can be deployed, scheduled and operated like a regular K8s workload.
🔹 Bring your own storage to Cube. The E2B-compatible Volume framework uses Create, Destroy, Attach and Detach hooks to decouple sandbox storage from any specific backend.

🥳We just open-sourced Cube Sandbox! An instant, concurrent, secure and lightweight sandbox runtime for AI Agents.
Built with RustVMM and KVM, it achieves the perfect balance of security and performance:
→ Sub-60ms cold start (2.5-50x faster)
→ Under 5MB memory overhead per instance (6x less memory)
→ Dedicated kernel per sandbox (hardware-level isolation)
→ Thousands of concurrent sandboxes per node
→ 100% E2B SDK compatible. Swap the endpoint, zero code changes
Full-stack capability, one-click deployment. 3 steps to spin up your own private AI sandbox 👇 🔗
