AI is supercharging app development for everyone, but we need a safe way to run untrusted, LLM-written code. We’re introducing Sandboxes, which let your Worker run actual processes in a secure, container-based environment.

import { getSandbox } from "@cloudflare/sandbox";
export { Sandbox } from "@cloudflare/sandbox";

export default {
  async fetch(request: Request, env: Env) {
    const sandbox = getSandbox(env.Sandbox, "my-sandbox");
    return sandbox.exec("ls", ["-la"]);
  },
};

Methods

• exec(command: string, args: string[], options?: { stream?: boolean })...
