If your agent executes code, you want to run it in an isolated environment. I learned this the hard way. I also know a couple of people who let OpenClaw go nuts and had to wipe out their laptops after a few days to clean up the mess. Two rules you must always follow: 1. Agent that runs code → isolated environment 2. Agent that controls a browser → isolated environment But that generates a new problem: that environment has to start quickly, use as little memory as possible, and give you enough control to operate it. This is hard to achieve, but you don't need to reinvent the wheel: Cube Sandbox is an open-source MicroVM sandbox developed by Tencent Cloud. Think of it as a production-grade agent infrastructure that you can use to run agents at scale. Cube Sandbox uses RustVMM and KVM to run each sandbox with hardware-level isolation. • It cold-starts in under 60ms • It uses less than 5MB of RAM overhead • You can launch tens of thousands of sandboxes within a minute Here is what you can do with it: 1. Capture, clone, and restore sandbox state with snapshots and rollback 2. Deploy sandbox clusters through Kubernetes 3. Run workloads on ARM infrastructure 4. Observe what happens inside agent executions 5. Govern ingress and egress traffic 6. Persistent volumes and cross-machine pause/resume Here is the GitHub repository: You can inspect the code and try it out with your own agent workflow. #ad#
