Cloudflare Sandbox

The Sandbox SDK enables you to run untrusted code securely in isolated environments. Built on Containers, Sandbox SDK provides a simple API for executing commands, managing files, running background processes, and exposing services — all from your Workers applications.

Sandboxes are ideal for building AI agents that need to execute code, interactive development environments, data analysis platforms, CI/CD systems, and any application that needs secure code execution at the edge. Each sandbox runs in its own isolated container with a full Linux environment, providing strong security boundaries while maintaining performance.
