TencentCloud/CubeSandbox

• highreadme#1

  Strengthen the README's opening to explicitly position for AI agent code execution

  Why:

  CURRENT

  Cube Sandbox is a high-performance, out-of-the-box secure sandbox service built on RustVMM and KVM. It supports both single-node deployment and easy scaling to multi-node clusters. It is compatible with the E2B SDK and can create a hardware-isolated, fully serviceable sandbox in under 60ms with less than 5MB of memory overhead.

  COPY-PASTE FIX

  Cube Sandbox is a high-performance, out-of-the-box secure sandbox service specifically designed for AI Agents. Built on RustVMM and KVM, it provides hardware-isolated microVMs that combine the strong security of KVM with the lightweight, fast-starting, and container-like user experience of OCI-compatible containers. This enables instant, concurrent, and secure execution of untrusted AI agent code, creating a fully serviceable sandbox in under 60ms with less than 5MB of memory overhead, far surpassing generic container or VM solutions for AI workloads. It supports both single-node deployment and easy scaling to multi-node clusters, and is compatible with the E2B SDK.
