CubeSandbox
Tencent Cloud's E2B-compatible microVM sandbox service for AI agents.
Cube Sandbox is a secure sandbox service from Tencent Cloud built on RustVMM and KVM. It is compatible with the E2B SDK and creates hardware-isolated sandboxes in under 60 ms, deploying on a single node or scaling to multi-node clusters, including Kubernetes. Releases have added the CubeCoW copy-on-write snapshot engine for cloning and rollback, a credential vault that keeps keys out of the sandbox, AutoPause/AutoResume, network policy hardening and cross-node pause/resume with an S3 backend.
