SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Deno sandboxes provide secure, isolated environments for running untrusted code, enabling safe experimentation and multi-tenant execution.

Core Features & Use Cases

  • Isolated execution: Each sandbox runs in its own microVM with separate filesystem, network, and process space.
  • Safe resource control: Enforce permissions and lifecycle handling to prevent leaks and misuse.
  • Use Case: Deploy AI agents or code playgrounds that run user-provided code without risking the host system.

Quick Start

Create a sandbox with secure defaults and run untrusted code inside it.

FAQPage Schema
How do I securely execute untrusted code in an isolated environment?

Securely executing untrusted code requires isolated Deno sandboxes that run each process in a separate Firecracker microVM with distinct filesystem, network, and process space. This prevents user-submitted code from affecting the host system.

What is the best way to run AI agent tool execution without risking the host system?

Running AI agent tool execution safely involves deploying isolated Deno sandboxes with strict permission enforcement and automatic lifecycle disposal. This container-like isolation prevents resource leaks and misuse from untrusted code evaluation.

Can I use Firecracker microVMs for multi-tenant code playground isolation?

Firecracker microVMs enable multi-tenant code playground isolation by providing each Deno sandbox with its own separate filesystem and network space. This architecture supports safe experimentation across isolated environments without host risk.

How does sandbox lifecycle management work for user-submitted code evaluation?

Sandbox lifecycle management for user-submitted code evaluation handles automatic disposal of isolated Deno environments. This prevents resource leaks by safely terminating microVMs after code execution completes, ensuring safe resource control.

Does Deno sandbox code execution support controlled permissions and safe command execution?

Deno sandbox code execution supports controlled permissions and safe command execution within isolated microVMs. It enforces strict resource control to prevent unauthorized access while maintaining separate process spaces for untrusted code.

When do I need container-like isolation instead of standard runtime permissions for code execution?

Container-like isolation using Firecracker microVMs is necessary for code execution when handling untrusted code that requires strict filesystem, network, and process space separation beyond standard Deno runtime permissions.
