Don't run AI agents unsandboxed: 5-step isolation workflow with open-source CubeSandbox
EXM7777 · x · 2026-09-03
Running AI agents with full machine access is 'gambling your business,' the author warns, and lays out a concrete isolation workflow built on the open-source CubeSandbox project (v0.7, self-hosted, preview):
- Give every agent its own sandbox
- Sandboxes launch instantly and are light enough to run thousands per server
- Save checkpoints so you can roll back and retry after a bad command
- Clone a successful sandbox and fan out 10 parallel agents from that exact state, keeping the best result
- Scale past one machine — the new version can freeze a sandbox on one server and resume it elsewhere
