Since launching Cloudflare Sandboxes in June, we’ve enhanced AI agents’ coding capabilities while ensuring secure environments for development. Sandboxes allow agents to clone repositories, build code, and run development servers efficiently. They solve key challenges: rapid sandbox creation (burstiness), quick state restoration for sessions, secure credential handling, and user-friendly controls. We collaborated with partners like Figma, which leverages Sandboxes for running user-authored code securely.
Recent updates include secure credential injection, pseudo-terminal support for real-time interactions, and persistent code interpreters for stateful execution in Python, JavaScript, and TypeScript. New features like background processes and live preview URLs enable agents to share development outputs instantly. Filesystem watching optimizes iteration speed, while our snapshot feature allows quick state restoration without idle compute costs.
With increased capacity and a new Active CPU Pricing model, users can efficiently run thousands of concurrent instances. Experience the evolution of development environments with Cloudflare Sandboxes today!
