Instant, Concurrent, Secure & Lightweight Sandbox for AI Agents. - TencentCloud/CubeSandbox
Summary

TencentCloud open-sourced CubeSandbox, a secure sandbox service for AI agents built on RustVMM and KVM that creates hardware-isolated environments in under 60ms with less than 5MB memory overhead. It supports single-node or multi-node cluster deployment, is compatible with the E2B SDK for drop-in migration, and includes features like AutoPause/AutoResume, snapshot/clone/rollback via a Copy-on-Write engine, credential vault, and egress control. Benchmarks show sub-150ms P99 cold start latency even under 50 concurrent creations, with hardware-level isolation per Guest OS kernel to safely run untrusted LLM-generated code.
