Sandboxes start in milliseconds, enforce zero-trust security by default (no cloud credentials, no outbound network, read-only filesystem overlay), and run on already-allocated CPU/memory at no extra cost. Developers enable them with a single deployment flag and spawn them via subprocess calls. Integration is available with Google's Agent Development Kit (ADK) via a new CloudRunSandboxCodeExecutor, and with the vendor-agnostic ComputeSDK. Key use cases include LLM code interpreters, headless browsers for agents, and user-submitted code execution. ## Full article daily.dev links to this article rather than hosting it.

Deny-by-default egress is the right default for LLM code-interpreter use: outbound is the exfiltration vector, and most "just run the model's Python" setups forget to close it. ## Similar posts on daily.dev - [Let Your Agent Run Its Own Code Inside a Cloud Run Sandbox](https://daily.dev/posts/let-your-agent-run-its-own-code-inside-a-cloud-run-sandbox-rcioxcn32) · Medium · 0 upvotes · 0 comments - [Run Untrusted AI Agent Code Safely with Azure Container Apps Sandboxes](https://daily.dev/posts/run-untrusted-ai-agent-code-safely-with-azure-container-apps-sandboxes-og96gnzce) · InfoQ · 0 upvotes · 0 comments - [AWS, Google Cloud, Microsoft Azure, and Cloudflare now all offer agent sandboxes.
