Cube Sandbox is Tencent Cloud's open-source sandbox for AI agents: it runs agent-generated code in lightweight, microVM-isolated environments (each with its own guest kernel) that start instantly and run concurrently, with a template store and a web console at :12088. Apache-2.0 under Tencent's standard open-source notice; bundled third-party components keep their own licenses.
