Overview
Deno has launched Deno Sandbox, a hosted code execution platform that secures API secrets from code running inside sandboxes. Unlike traditional sandboxes, it uses a proxy system where secrets are replaced with placeholders, preventing malicious code from accessing real API keys.
Key Facts
- Accessible from Python and JavaScript - eliminates language barriers for sandbox integration
- Up to 4GB RAM, 2 vCPUs, 10GB storage, 30-minute sessions - handles compute-intensive workloads in isolation
- Network access restricted to specified domains - prevents unauthorized external communications
- Secret placeholders replaced by proxy during API calls - malicious code cannot steal your API keys
- Secrets never directly accessible within sandbox environment - prompt injection attacks can’t exfiltrate credentials
- Supports persistent volumes and custom snapshots - maintains state across sandbox sessions
Why It Matters
This matters because it solves a critical security problem in AI applications where untrusted code execution could expose sensitive API credentials, enabling safer deployment of AI agents and code generation tools.
