GitHub TypeScript NOASSERTION

Description

A TypeScript SDK for running sandboxed code environments on Cloudflare's edge network, designed for AI agents and untrusted code execution.

Key Features

  • Edge sandboxes - Run lightweight microVM sandboxes on the Cloudflare global network with low cold-start latency
  • Multi-language execution - Run Python, Node.js, Java, and Bash code in isolated environments
  • Snapshots and restore - Snapshot sandbox state and resume for long-running agents
  • File and process APIs - File read/write, command execution, and streaming output
  • Agent tool integration - Native @tool decorator to register sandbox actions as AI agent tools

Use Cases

💡 Expose secure code execution tools to LLM-powered agents
💡 Run untrusted user-generated scripts at the edge as a code interpreter backend
💡 Provide isolated execution environments for workflow automation
💡 Plug into RAG and data pipelines for preprocessing and computation
