Agents have their own computers with Sandboxes GA

Cloudflare Sandboxes is now generally available, providing AI agents with isolated environments to develop and run code safely at scale.

• •Secure credential injection enables authenticated API calls without agents accessing raw credentials through a programmable egress proxy
• •PTY support offers real terminal sessions over WebSocket compatible with xterm.js, allowing agents to debug interactively like human developers
• •Persistent code contexts maintain state across multiple executions for Python, JavaScript, and TypeScript, similar to Jupyter notebooks
• •Background processes and live preview URLs let agents start development servers and share public links without leaving the conversation
• •Filesystem watching with inotify enables event-driven iteration as agents modify files, triggering automated rebuilds and tests
