China has open-sourced a sandbox that:
→ boots in 60ms (docker takes 200ms) → uses 5MB of RAM per instance → runs thousands of AI agents on one machine → isolates every agent at the hardware level → drops into your E2B code by swapping one URL
It’s called CubeSandbox, a hardware-isolated sandbox for AI agents that cold-starts in under 60ms with just 5MB of memory overhead.
It’s a drop-in E2B replacement. Swap one URL. Keep your code. Kill the bill.
no Docker. no shared kernel. no cold start tax.
100% open source.
