2026-09-01 / thought-leaders-researcherTencent's CubeSandbox hits v0.7.0 with cross-node pause/resume and sub-60ms cold starts for agent sandboxesTencent Cloud's CubeSandbox, an Apache-2.0 microVM sandbox for AI agents built on RustVMM and KVM, shipped v0.7.0 on Aug 28 adding cross-node pause/resume and control-plane separation. The project claims an average cold start under 60ms, sub-150ms delivery under high concurrency, and under 5MB memory overhead per sandbox, with pause and resume at hundred-millisecond granularity. It has 11.6k stars and 1.1k forks since the April 2026 v0.1.0 release, which puts a credible open alternative under the hosted agent-sandbox services.
