TencentCloud/CubeSandbox

Most AI agents today can run code… But where do they run it safely? That's the missing layer. Meet CubeSandbox (Tencent Cloud) → https://t.co/68lHA7qs0s An open-source secure execution environment for AI agents - fast, isolated, and built for scale. ⚙️ Key features: • Hardware-level isolation (KVM-based) → each agent runs safely in its own environment • Ultra-fast startup (<100ms) → near instant sandbox execution • Massive concurrency → thousands of sandboxes per server • Lightweight (~5MB per instance) → efficient resource usage • E2B API compatible → drop-in replacement for existing agent infra • Built with Rust + KVM + QEMU for performance + safety • Full stack: CubeMaster, Cubelet, networking, API layer 🧠 What it actually does: Runs AI-generated code in isolated sandboxes so agents can: → execute code → access files → run tools without risking your system 💡 Why it matters: Without this: AI agents = dangerous With this: AI agents = safe to execute in production 🔄 Big shift: LLM agents → Secure execution environments This is one of the most important missing layers in AI infra.
