🔓 Tencent Open-Sources Cube Sandbox — AI Agent Playground That Boots in 60ms

Every AI agent needs a safe room to run code without breaking your real systems. The problem? Most sandbox solutions are proprietary, slow to start, and lock you in.

Tencent Cloud just changed that.

They've open-sourced **Cube Sandbox** — the industry's first open-source sandbox with hardware-level isolation that cold-starts in under 60 milliseconds. That's 2.5x faster than the industry average.

🎯 Why it matters:

• **60ms cold start** — each sandbox spins up almost instantly
• **Under 5MB memory** per instance — run thousands without sweating
• **2,000+ concurrent sandboxes** with 100,000+ scheduling capacity
• **E2B compatible** — switch from proprietary solutions by changing one environment variable, zero code changes
• **Works with Manus, OpenAI Agents SDK**, and the entire E2B ecosystem out of the box

Think of it as a blast-proof lab that builds itself in a blink, lets your AI experiment freely, and disappears when done — all for free.

For developers building AI agents, this eliminates vendor lock-in and gives a production-grade alternative that's fast, secure, and open. When a company like Tencent open-sources infrastructure this competitive, the entire ecosystem levels up.
