What are Hopx Sandboxes?

Hopx Sandboxes are secure, isolated cloud virtual machines that enable you to run AI-generated code, execute multi-language programs, and perform complex computations in production-like environments. Each sandbox is a fully isolated microVM that starts in ~100ms and provides complete filesystem access, code execution capabilities, desktop automation, and real-time streaming — all accessible through production-ready SDKs in Python and JavaScript/TypeScript. With Hopx Sandboxes, you can execute code in Python, JavaScript/TypeScript, Bash (shell), Go, .NET (C#), Java, and PHP; manage files and directories; run shell commands; control processes; automate desktop GUI interactions via VNC; stream execution output in real-time; build custom VM templates; and integrate seamlessly with LLMs, CI/CD pipelines, and data workflows — all with enterprise-grade security, automatic retries, error handling, and comprehensive observability.
  • Isolation: Each sandbox runs in a separate VM for strong security boundaries.
  • Ephemeral: Sandboxes start in ~100ms and can be discarded or rebuilt at any time.
  • Versatile: Ideal for code execution by LLMs, automated testing, data analysis, desktop automation, and more.
  • Managed: No DevOps or server setup—just run your code through simple SDK calls.
  • Templatized: Sandboxes can be created from pre-configured templates or custom-built templates using our fluent template builder API.
  • Multi-Language SDKs: Production-ready SDKs for Python and JavaScript/TypeScript with consistent APIs and full feature parity.
