Deno Sandbox – Securely run untrusted code with controlled network and secrets

Summary: Deno Sandbox runs untrusted code in secure Linux microVMs with instant startup, strict network policies, and isolated secrets. It enables safe execution of LLM-generated code that requires API keys and external network access without human review.

What it does

It isolates code execution using microVMs, enforces network egress controls, and protects secrets from exfiltration. Code can then be deployed directly to Deno Deploy without rebuilding.

Who it's for

Developers running LLM-generated or untrusted code that needs secure API access and network restrictions.

Why it matters

It prevents unauthorized data leaks and secures execution of dynamic code requiring sensitive credentials and network access.
